PIN FUNCTIONS Pin No. Symbol Pin Voltage Description 3 RF Input 2.5 Pin 3 is the input pin of the RF amplifier. Pin 4 should be connected to GND via a bypass capacitor. 4 RF Bypass 2.5 Equivalent Circuit VCC To MIX To MIX 3 5 Mixer IF 1.1 4 Pin 5 is the output pin of the Mixer IF. The output signal comes from the mixer unit via the AGC amplifier. This output pin features low impedance because it is the output of an emitter-follower. VCC MIX 6 IF Bypass 2.1 Pins 6 and 7 are the input pins to the IF amplifier. These two inputs are internally connected to the base of each pair of transistors in the differential amplifier. Pin 6 should be connected to GND via a bypass capacitor. 7 IF Input 2.1 8 Bypass 2.1 Pin 8 is connected to the feedback loop of the IF amplifier. This pin should be connected to GND via a bypass capacitor to stabilize the DC bias. 13 IF Out 1.4 Pin 13 is the output pin of the IF amplifier. This output pin features low impedance because it is the output of an emitter-follower. 8 5 AGC Amp VCC 13 7 6 UPC2753GR PIN FUNCTIONS Pin No. Symbol Pin Voltage 16 VAGC 0 to 2.4 (Supply voltage) Description Pin 16 is the gain control pin for the AGC amplifier. The gain of the AGC amplifier is controlled by the applied voltage on this pin. Equivalent Circuit VCC MIX AGC Amp RF 5 LO 16 Pins 17 and 18 are the LO input pins of the mixer. The LO Bypass pin should be connected to GND via a bypass capacitor. 17 LO Bypass 2.5 18 LO Input 2.5 15 VCC (DC) — Pin 15 is the VCC supply pin for the downconverter block. This pin is independent of the VCC pin for the IF amplifier. Apply 3 V to pin 15. — 14 VCC (IF) — Pin 14 is the VCC supply pin for the IF amplifier. This pin is independent of the VCC pin for the downconverter unit. Apply 3 V to pin 16. — 2 9 12 19 GND — This pin is the ground pin for the entire chip. Therefore the ground of the IF downconverter and IF amplifier blocks are not separated. The ground pattern to be connected to this pin should be formed as wide as possible to minimize its impedance. — 10 11 GND — Pins 10 and 11 are not connected to the internal circuits. Connecting these pins to GND is recommended, though these pins may be left unconnected. — 1 NC — — 20 NC Pins 1 and 20 are the output pins of the mixer block. These pins are used to monitor the signal output from the IF amplifier and to be input to the AGC amplifier. When the IC is actually used, these pins should be left opened.
