Operation in excess of any one of these parameters may result in permanent damage. 2. Mounted on a 50 x 50 x 1.6 mm epoxy glass PWB (TA = +85°C). TEST CIRCUIT/BLOCK DIAGRAM UPC2757TB, UPC2758TB All Capacitors 0.1 µF UPC2757TB, UPC2758TB RECOMMENDED OPERATING CONDITIONS SYMBOLS PARAMETERS UNITS MIN TYP MAX VCC Supply Voltage V 2.7 3.0 3.3 TOP Operating Temperature °C -40 +25 +85 PLO LO Input Level dBm -15 -10 0 LO In VPS VCC IF Out RF In 3 2 1 4 5 6 Pin Pin Applied Pin Description Internal No. Name Voltage Voltage Equivalent Circuit (V) (V) 1RFIN — 1.2 Signal input pin to double balanced mixer. This pin must be coupled to the signal source with a blocking capacitor. 2 GND 0 — Ground pin. This pin should be connected to system ground with minimum inductance. Ground pattern on the board should be formed as wide as possible. 3LOIN — 1.3 LO input pin. The LO buffer is designed as a differential amplifier. Recommended input level is -15 to 0 dBm. 4VPS VCC / GND — Power save control pin can control the On/Sleep state with bias as follows: VPS (V) STATE ≥2.5 ON 0 to 0.5 SLEEP Rise time/fall time using this pin is approximately 10 µs. 5VCC 2.7 to 3.3 — Power supply pin. This pin should be externally equipped with a bypass capacitor to minimize ground impedance. 6IFOUT — 1.7 Output of single-ended push-pull IF buffer amplifier. This is an emitter-follower output with low impedance. This pin must be coupled to the next stage with a blocking capacitor. PIN DESCRIPTION From LO VCC To IF Amp 1 3 Mixer VCC VCC 4 6 |
