Schematic
With device marking oriented right side up, RF IN is on the left and RF OUT is on the right.
Blue wire is collector DC voltage input (pin 1). VCC= +3.5V nominal.
Brown wire is reference DC voltage input (pin 3). Vref=+ 2.7V nominal to obtain Iccq= 80mA.
Operation at lower or higher quiescent currents can be achieved by decreasing or increasing Vref
voltage relative to +2.7V.
First apply +3.5V to the collector supply (blue wire). Next apply +2.7V to the reference supply to brown
wire. Quiescent collector current with no RF applied will be about 80 mA. Reference supply current with
or without RF applied will be about 13 mA. When turning amplifier off, reverse power supply sequence.
Apply -20dBm RF input power at PCS frequency (1850 -1910MHz). After making any initial small signal
measurements at this drive level, input power may be increased up to a maximum of +6dBm for large
signal, single-tone or digital CDMA measurements. Do not exceed +6dBm input power.
