Instructions
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= 80 mA. 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 -20 dBm RF input power at WCDMA frequency (1920-1980 MHz). After making any initial small signal
measurements at this drive level, input power may be increased up to a maximum of +6 dBm for large signal,
single-tone or digital WCDMA measurements. Do not exceed +6 dBm input power.
