AD8343:  DC-to-2.5 GHz High IP3 Active Mixer

Product Details

The AD8343 is a high-performance broadband active mixer. With wide bandwidth on all ports and very low intermodulation distortion, the AD8343 is well suited for demanding transmit applications or receive channel applications.

The AD8343 provides a typical conversion gain of 7 dB. The integrated LO driver supports a 50 Ω differential input impedance with low LO drive level, helping to minimize external component count.

The open-emitter differential inputs can be interfaced directly to a differential filter or driven through a balun (transformer) to provide a balanced drive from a single-ended source.

The open-collector differential outputs can be used to drive a differential IF signal interface or convert to a single-ended signal through the use of a matching network or transformer. When centered on the VPOS supply voltage, the outputs swing ±1 V.

The LO driver circuitry typically consumes 15 mA of current. Two external resistors are used to set the mixer core current for required performance, resulting in a total current of 20 mA to 60 mA. This corresponds to power consumption of 100 mW to 300 mW with a single 5 V supply.

The AD8343 is fabricated on Analog Devices, Inc.’s high-performance 25 GHz silicon bipolar IC process. The AD8343 is available in a 14-lead TSSOP package. It operates over a −40°C to +85°C temperature range. A device-populated evaluation board is available.

    ADIsimPLL™- Version 3.60.10
    ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.

    AD8343 S-Parameters  (htm, 35 kB)
    The S2P file provides differential impedance measurements. The S2P port assignments are as follows:
      Port 1: differential input
      Port 2: differential output

    In most cases the 2-port data will be all you'll need to develop matching networks for the AD8343. LO port can be considered as a 50 ohm input.

    Recommended PLL's for the AD8343

    • 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 AD8343
    • 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.
