Pin Table and Description
Description
RF input pin. Internal DC block.
Ground pin.
Power up/down control for 2nd stage amplifier. Apply V_CC to power on 2nd stage amplifier. Apply 0V to disable
2nd stage amplifier. Do not exceed V_CC + 0.5V. Connect to V_CC if not needed. Decoupling capacitor may be
desired on application board for control line noise.
No connection.
Power supply for the module. Recommending 1F decoupling cap on the application board.
Ground pin.
RF output pin. Internal DC block.
Gain control voltage; 0V to 3.3V range. Maximum gain at 0V. Recommending 0.1F decoupling on the applica-
tion board.
Center ground pads need to have a good thermal path on the application board. Use solder stencil pattern
shown in the document to define solder paste during assembly.
