Boasting a conversion loss of only 6 dB across its entire operating frequency range, the PE4120 high-linearity MOSFET Quad Mixer is a passive broadband device that performs functions ranging from frequency conversion to phase detection at up to 2.5 GHz. The chip is well suited for such applications as cellular/PCS telephone network base stations and cable modes. Operating across a frequency range from 500 MHz to 2.5 GHz, the device mixes a received RF signal with the output of a local oscillator to produce an intermediate frequency. For transmission, it mixes IF and LO signals to produce an RF output. Power loss during the conversion process is only 6 dB at any frequency, with a 20 dBm LO drive. Offered in 8-pin TSSOP and SOT-23 packages, the chip is priced at $1.00 each/10,000.
