DESCRIPTION
The UPC2768GR is a frequency converter manufactured with
the NESAT III process. This product consists of an RF input
amplifier, Gilbert cell mixer, Local Oscillator or LO buffer, IF
amplifier, external filter port, and IF output limiting amplifier.
The on-chip local oscillator only requires an external tank
circuit. The power save feature enables users to minimize
overall current consumption when dormant. This device was
specifically designed for low-cost second IF receivers, key-
less entry applications, security systems, GPS, and other low
power Part 15 mobile radios.

Notes:
1. Max freq. range is -3 dB from conversion gain for RF = 50 MHz
2. Down converter only (RFIN to mixer IFOUT).
3. PLO = -10 dBm external, or using internal LO.
4. Down converter and IF amp may be operated separately.
Typical ICC for down converter is 5.5 mA (pin 15). Typical ICC
for IF amp is 1.4 mA (pin 14).
