L BAND DOWN CONVERTER IC
DESCRIPTION
The µPC2782GR is a Silicon monolithic IC designed for use as L band downconverter. This IC consists of a
Gilbert cell mixer, two stages of LO buffering, local oscillator, external filter port, or a high output IF AGC amplifier and
IF output buffer amplifier.
The package is 20 pins SSOP (shrink small outline package) suitable for high-density surface mount.
FEATURES
• Broad band operation fRF = 0.9 to 2.1 GHz
• 25 dB variable gain IF AGC amplifier
• Low distortion IIP3 = +4.5 dBm (fRF = 2.1 GHz)
• Supply Voltage 5 V
• Packaged in 20 pins SSOP suitable for high-density surface mount
