1 BIPOLAR ANALOG INTEGRATED CIRCUIT / V, SUPER MINIMOLD SI MMIC DOWNCONVERTER FEATURES HIGH-DENSITY SURFACE MOUNTING: pin super minimold or SOT- package WIDEBAND OPERATION: RF =. GHz to. GHz = MHz to MHz BUILT-IN POWER SAVE FUNCTION SUPPLY VOLTAGE: =.7 TO. V DESCRIPTION The and are silicon RFICs manufactured using the NESAT III process. The devices consist of a mixer, an amplifier and an LO buffer amplifier. These devices are suitable as st downconverters for the receiver stage of cellular and other wireless systems. The is designed for low power consumption while the is designed for low distortion. The /8TB are pin compatible and have comparable performance to the larger UPC77T/8T, so they are suitable for use as a replacement to help reduce system size. The IC is housed in a pin super minimold or SOT- package. Stringent quality assurance and test procedures ensure the highest reliability and performance. = V, LO Power = - dbm MHz MHz ELECTRICAL CHARACTERISTICS (TA = C, = VPS =.

Signal input pin to double balanced mixer. This pin must be coupled to the signal source with a blocking capacitor. From LO To Amp GND 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. LOIN. LO input pin. The LO buffer is designed as a differential amplifier. Recommended input level is - to dbm. Mixer VPS / GND Power save control pin can control the On/Sleep state with bias as follows: VPS (V) STATE. ON to. SLEEP Rise time/fall time using this pin is approximately µs..7 to. Power supply pin. This pin should be externally equipped with a bypass capacitor to minimize ground impedance. OUT.7 Output of single-ended push-pull buffer amplifier. This is an emitter-follower output with low impedance. This pin must be coupled to the next stage with a blocking capacitor.
