AD8344:  400 MHz TO 1.2 GHz Active Receive Mixer

Product Details

Product Status:Recommended for New Designs

The AD8344 is a highly integrated SiGe active mixer optimized for receiver path down conversion. The input range spans from 400MHz to 1.2GHz allowing the part to be used in a broad range of applications including CDMA, GSM and TETRA infrastructure equipment.

The AD8344 provides a single ended 50W input impedance, on both the RF and LO input ports. An integrated LO driver allows for LO drive level, typically 0dBm.

The AD8344 can be optimized for power consumption and linearity through an external bias resistor connected to the EXRB pin. The AD8344 is specified for operation of a single +5V supply, consuming only 84mA, and 500µA in power down mode.

The AD8344 is fabricated on a high performance SiGe process. The device is packaged in a space saving 3mm x 3mm 16-lead LFCSP and fully specified over -40°C to +85°C temperature range.

Samples and evaluation boards, part number AD8344-EVAL, are available.

Suggested Companion Products

Recommended PLL's for the AD8344

  • For high performance with integrated VCO, we recommend the ADF4350.
  • For lower cost, power and size with integrated VCO, we recommend the ADF4360-X family of fixed frequency PLL's.
  • For higher performance, higher frequency and faster locktimes, we recommend the discrete Integer-N, ADF4106 or the discrete Fractional-N, ADF4153.
Recommended RF/IF Differential Amplifiers for the AD8344
  • For adjustable gain with external resistor, we recommend the AD8351.
  • For ultralow distortion and adjustable gain with external resistor, we recommend the AD8352.
  • For differential input/output digital gain amplifier, we suggest the AD8370 or the AD8375.
  • For ultralow distortion, pin strappable gain adjust, we suggest the ADL5561.
Recommended Power Solutions
  • For selecting voltage regulator products, use ADIsimPower.
