Table 4. Pin Function Descriptions Pin No. Mnemonic Description
1 RFIN RF Input. Requires a dc blocking capacitor. 2, 3, 6, 7 GND Ground. Connect these pins to a low impedance ground plane. 4 CB Low Frequency Bypass. A 1 µF capacitor should be connected between this pin and ground. 5 VPOS Power Supply for Bias Controller. Connect directly to external power supply. 8 RFOUT RF Output and Supply Voltage. DC bias is provided to this pin through an inductor that is tied to the external power supply. RF path requires a dc blocking capacitor. Exposed Paddle Exposed Paddle. Internally connected to GND. Solder to a low impedance ground plane. Rev.
