The MAX19794 dual general-purpose analog voltage variable attenuator (VVA) is designed to interface with 50Ω systems operating in the 10MHz to 500MHz frequency range. This device includes a patented control circuit that provides 22.4dB of attenuation range (per attenuator) with a typical linear control slope of 8dB/V.Both attenuators share a common analog control. They can be cascaded together to yield 44.7dB of total attenuation range with a typical combined linear control slope of 16dB/V (5V operation). Alternatively, the on-chip, 4-wire SPI-controlled 10-bit DAC can be used to control both attenuators. In addition, a step-up/down feature allows user-programmable attenuator stepping through command pulses without re-programming the SPI interface.The MAX19794 is a monolithic device designed using one of Maxim's proprietary SiGe BiCMOS processes. The part operates from a single +5V supply or alternatively operates from a single +3.3V supply. It is available in a compact 36-pin TQFN package (6mm x 6mm x 0.8mm) with an exposed pad. Electrical performance is guaranteed over the -40°C to +100°C extended temperature range.ApplicationsAutomatic Level Control (ALC)Broadband System Applications, Including Wireless Infrastructure Digital and Spread-Spectrum Communication SystemsGeneral Test EquipmentLineup Gain TrimMicrowave Point to Point SystemsReceiver Gain ControlTemperature Compensation CircuitsTransmitter Gain ControlVSAT/Satellite ModemsWCDMA/LTE, TD-SCDMA/TD-LTE, WiMAX®, cdma2000®, GSM/EDGE and MMDS Base Stations

The MAX2042A single, high-linearity upconversion/downconversion mixer provides up to +33dBm input IP3, 7.25dB noise figure, and 7.2dB conversion loss for 1600MHz to 3900MHz GSM/EDGE, CDMA, TD-SCDMA, WCDMA, LTE, TD-LTE, WiMAX™, and MMDS wireless infrastructure applications. With an ultra-wide 1300MHz to 4000MHz LO frequency range, the IC can be used in either low-side or high-side LO injection architectures for virtually all 1.7GHz to 3.5GHz applications (for a 2.5GHz variant tuned specifically for low-side LO injection, refer to the MAX2042). In addition to offering excellent linearity and noise performance, the IC also yields a high level of component integration. This device includes a double-balanced passive mixer core, an LO buffer, and on-chip baluns that allow for single-ended RF and LO inputs. The IC requires a nominal LO drive of 0dBm, and supply current is typically 140mA at VCC = 5.0V or 122mA at VCC = 3.3V. The MAX2042A is pin compatible with the MAX2042 2000MHz to 3000MHz mixer. The MAX2042A is also pin similar with the MAX2029/MAX2031/MAX2033 650MHz to 1550MHz mixers, the MAX2039/MAX2041 1700MHz to 3000MHz mixers, and the MAX2044 2300MHz to 4000MHz mixer, making the entire family of upconverters/downconverters ideal for applications where a common PCB layout is used for multiple frequency bands. The MAX2042A is available in a compact, 20-pin TQFN package (5mm x 5mm) with an exposed pad. Electrical performance is guaranteed over the extended TC = -40°C to +85°C temperature range.Applications1.8GHz/1.9GHz GSM/EDGE/CDMA Base Stations2.1GHz WCDMA/LTE Base Stations2.3GHz TD-SCDMA/TD-LTE Base Stations2.5GHz WiMAX and LTE Base Stations2.7GHz MMDS Base Stations3.5GHz WiMAX and LTE Base StationsFixed Broadband Wireless AccessMilitary SystemsPrivate Mobile RadiosWireless Local Loop

The MAX2173 is a highly integrated direct-conversion tuner for digital audio broadcast (DAB) and terrestrial digital multimedia broadcast (T-DMB) applications in the 168MHz to 240MHz (VHF band-III) and 1452MHz to 1492MHz (L-band) frequency bands. For FM and DRM+ reception, a low-IF conversion is used, covering a frequency range of 76MHz to 108MHz (FM band). The design integrates lowpass filters, enabling low-power tuner-on-board designs. The mixer and lowpass filtering are followed by a dual ADC and digital filtering. The digital filtering reduces the output data rate and eases the processing load on the DSP. The resulting bit stream is driven off-chip via an I²S format bus.An integrated digitally controlled crystal oscillator provides more than ±50ppm control range, eliminating the need for a VCXO. The MAX2173 also provides a buffered-reference clock output at the crystal frequency (fREF) or fREF/3.Two LDOs are integrated into the MAX2173. The 1.6V LDO can be used to power the internal 1.6V circuitry. External circuits can be powered using the 1.2V LDO, eliminating the need for a stand-alone 1.2V regulator.The MAX2173 is available in a 40-pin TQFN package (6mm x 6mm) with an exposed pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.ApplicationsAutomotive DAB ProductsFixed and Mobile DAB/FM ProductsT-DMB/FM Products

The MAX2180A is a highly integrated AM/FM variable-gain low-noise amplifier ideal for use in automotive active antenna applications. The device features separate AM and FM signal paths, each providing 30dB of gain range, controlled by individual on-chip power detectors. The AM signal path covers a 148kHz to 30MHz input frequency range, while the FM signal path covers 65MHz to 162.5MHz.The device integrates a voltage regulator and pass transistor, allowing operation using battery voltages in the +6V to +24V range. On-chip thermal protection automatically limits junction temperatures during extreme thermal conditions.The device is available in a small, 4mm x 4mm, TQFN package and operates over the extended industrial temperature range (-40°C to +85°C).ApplicationsAutomotive Active Antenna

The MAX2612–MAX2616 is a family of high-performance broadband gain blocks designed for use as a PA predriver, low-noise amplifier, or as a cascadable 50Ω amplifier with up to +19.5dBm output power. These devices are suited for many applications that include cellular infrastructure, private or commercial microwave radios, and CATV or cable modems. The operating frequency range extends from 40MHz to 4000MHz. The amplifier operates on a +3V to a +5.25V supply with input and output ports internally matched to 50Ω. The device family is available in a pin-to-pin compatible, compact 2mm x 3mm TDFN lead-free package.ApplicationsAutomotiveCellular InfrastructureMicrowave RadioTest and MeasurementWireless LAN

The MAX2686L /MAX2693L low-noise amplifiers (LNAs) are designed for GPS L1, Galileo, and GLONASS applications. Designed in Maxim’s advanced SiGe process, the devices achieve high gain and low noise figure while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. Both devices include an internal LDO ideal for battery-powered applications. For current-sensitive applications, the MAX2693L achieves excellent performance while consuming only 1.8mA current.The devices operate from a +1.6V to +4.2V single supply.
