The ADMV4530 is a highly integrated upconverter with an in-phase/quadrature (I/Q) mixer that is ideally suited for next generation Ka band satellite communications.An integrated low phase noise, fractional-N phase-locked loop (PLL) with a voltage controlled oscillator (VCO) and internal 2? multiplier generate the necessary on-chip local oscillator (LO) signal for the I/Q mixer, eliminating the need for external frequency synthesis. The VCO uses an internal autocalibration routine that allows the PLL to select the necessary settings and locks in approximately 100 ?s.The single-ended reference input to the PLL operates up to 500 MHz and features internal reference dividers and a multiplier for added flexibility. Additionally, the phase frequency detector (PFD) comparison frequency can be up to 250 MHz for integer mode and 160 MHz for fraction-N mode.The upconverter consists of an I/Q mixer that can operate in either I/Q mode with 500 MHz of bandwidth or in IF mode up to 3 GHz of bandwidth, which allows various radio architectures and backward compatibility with legacy systems.Immediately following the I/Q mixer are stages of gain and variable attenuation. The configuration can achieve a minimum 1 dB compression point (P1dB) compression point of 19 dBm, eliminating the need for external stages of gain.A programmable 4-wire serial port interface (SPI) allows adjustment of the quadrature phase for optimum sideband suppression. In addition, the SPI allows nulling of LO feedthrough in IF mode. In I/Q mode, the LO feedthrough can be nulled by applying external dc offset to the differential baseband I/Q inputs.An IF automatic gain control (AGC) adjusts the IF variable gain amplifier (VGA) to compensate for input power variations. During normal operation, this AGC feature can be enabled or disabled via the SPI. When disabled during normal operation, the AGC feature only works on a test tone during power-down mode to track temperature variations.The ADMV4530 upconverter comes in a RoHs compliant, 6 mm ? 6 mm, 40-terminal land grid array (LGA) package. The ADMV4530 operates over the ?40?C to +85?C case temperature range.Applications Satellite communication Point to point microwave communication

ADI 47.2 GHz to 48.2 GHz TX/RX Dual Polarization Beamformer

The ADMV4821 is a silicon germanium (SiGe), 24 GHz millimeterwave (mmW) to 29.5 GHz mmW 5G beamformer. The RF IC is highly integrated and contains 16 independent channels with both transmit and receive functionality. The ADMV4821 supports eight horizontal and eight vertical polarized antennas via the independent RFV and RFH inputs/outputs common pins.In transmit mode, both the RFV and RFH input signals are split via two independent 1:8 power splitters and pass through the eight, independent, corresponding transmit channels. In this mode, each channel includes a vector modulator (VM) to control the phase and two digital variable gain amplifiers (DVGAs) to control the amplitude.In receive mode, input signals pass through two sets of eight receive channels (either vertical or horizontal) and are combined via one independent 8:1 combiner connected to the RFV pin and one independent 8:1 combiner connected to the RFH pin. In this mode, each channel includes a VM to control the phase and a DVGA to control the amplitude.The VM provides a full 360? phase adjustment range in either transmit or receive mode. The VM provides six bits of resolution for 5.625? phase steps.In transmit mode, the total DVGA dynamic range adjustment range is 32.4 dB. The DVGAs provide five bits or six bits of resolution, resulting in 1.0 dB or 0.5 dB amplitude steps, respectively.In receive mode, the DVGA allows for 17.1 dB of dynamic range adjustment. The DVGA also provides six bits of resolution, resulting in 0.5 dB amplitude steps. The DVGAs provide a flat phase response across the full gain range.The transmitter channels contain individual power detectors to detect and calibrate the gain for each channel as well as the channel to channel gain mismatch. Directly connect the ADMV4821 RF ports to a patch antenna to create a dual polarization mmW 5G subarray.Users can program the ADMV4821 by using a 3-wire or 4-wire serial port interface (SPI). The integrated on-chip low dropout (LDO) regulator generates the 1.8 V supply for the SPI circuitry to reduce the number of supply domains required. There are various SPI modes to enable fast startup and control during normal operation.Users can either set the amplitude and phase for each channel individually or program multiple channels simultaneously by using the on-chip memory for beamforming. The on-chip memory can store up to 256 beam positions, which can be allocated for either transmitter or receiver mode in any combination. In addition, four address pins allow SPI control of up to 16 devices on the same serial lines. Dedicated horizontal and vertical polarization load pins also synchronize all devices in the same array. There is a horizontal and vertical polarization transmit and receive mode control pins (TRXV and TRXH) for fast switching between transmit and receive mode.The ADMV4821 comes in a compact, thermally enhanced 10 mm ? 10 mm, RoHs compliant land grid array (LGA) package. The ADMV4821 operates over the ?40?C to +95?C case temperature range. This LGA package allows users to heat-sink the ADMV4821 from the top side of the package for the most efficient thermal heatsinking and to allow flexible antenna placement on the opposite side of the printed circuit board (PCB).Throughout the figures in the data sheet, Tx means transmit (or transmitter) and Rx means receive (or receiver).APPLICATIONS5G applicationsBroadband communicationTest and measurementAerospace and defense

The ADN8833 is a monolithic H-bridge TEC driver with integrat-ed 1 A power MOSFETs. It has a linear power stage with the linear driver (LDR) output and a pulse-width modulation (PWM) power stage with the SW output. Depending on the control voltage at the CONT input, the ADN8833 drives current through a TEC to settle the temperature of a laser diode or a passive component attached to the TEC module to the programmed target temperature.The control voltage applied to the CONT input is generated by a digital-to-analog converter (DAC) closing the digital proportional, integral, derivative (PID) loop of temperature control system.The internal 2.5 V reference voltage provides a 1% accurate output that is used to bias a voltage divider network to program the maximum TEC current and voltage limits for both the heating and cooling modes. It can also be a reference voltage for the DAC and the temperature sensing circuit, including a thermistor bridge and an analog-to-digital converter (ADC).APPLICATIONS TEC temperature control Optical modules Optical fiber amplifiers Optical networking systems Instruments requiring TEC temperature control
