Overview
DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC1694GR GENERAL PURPOSE HIGH FREQUENCY WIDEBAND IC FOR FREQUENCY DOWN-CONVERTER DESCRIPTION The µPC1694GR is Silicon monolithic IC for down-converter that is capable of operating up to 1 GHz.
This IC consists of double balanced mixer (DBM), local oscillator and IF amplifier.
Furthermore, combination with the µPC1663G (high-speed video amp) enables it to be applied to a FM demodulation circuit such as DBS tuner.
The package is 14-pin SOP suitable for surface mounting.
FEATURES • Satisfactory 1% cross-modulation distortion characteristics: CM = 103 dBµ @ fdes = 200 MHz • Wide band operation: f ≤ 1 GHz • Easy to connect with varactor diode due to balanced amplifier oscillator • Single-end push-pull IF amplifier suppresses fluctuation in output impedance • Supply voltage: 5 V • Packaged in 14-pin SOP suitable for smaller mounting area APPLICATIONS • Tuners for TV and VCR ORDERING INFORMATION Part Number Package 14-pin plastic SOP (225 mil) Supplying Form Embossed tape 16 mm wide.
Pin 1 indicates pull-out direction of tape.
