With device marking oriented right side up, RF IN is on the left and RF OUT is on the right.
Vcc = +3.4V nominal. Vref = +3.0V nominal to obtain Iccq = 80 mA. Operation at lower or higher quiescent currents can be
achieved by decreasing or increasing Vref voltage relative to +3.0V.
First ground the PCB (GND terminal) and apply +3.4V to the collector supply terminals (Vcc1, Vcc2). Next apply +3.0V to
the reference supply (Vref terminal). Quiescent collector current with no RF applied will be about 80 mA. Reference supply
current with or without RF applied will be about 15 mA. When turning amplifier off, reverse power supply sequence.
Apply -20dBm RF input power at Cellular frequency (824-849 MHz). After making any initial small signal measurements at
this drive level, input power may be increased up to a maximum of +7dBm for large signal, analog (AMPS) or digital CDMA
measurements. Do not exceed +7dBm input power.
