Pin Names and Description Pin Function Description 1VRX Switch control for Rx mode 2RX RF Output is internally matched to 50 and DC blocked. 3GND Ground connection 4PDET Power detector provides an output voltage proportional to the RF output power level. 5VREG3 Third stage bias voltage. This Pin requires regulated supply for best performance. 6VREG2 Second stage bias voltage. This Pin requires regulated supply for best performance. 7VREG1 First stage bias voltage. This Pin requires regulated supply for best performance. 8PDOWN Power down pin. Apply <0.3VDC to power down the three power amplifier stages. Apply 1.75VDC to 5.0VDC to power up. If function is not desired, Pin may be connected to VREG. 9GND Ground connection 10 TXIN RF input is internally matched to 50 and DC blocked. 11 GND Ground connection 12 GND Ground connection 13 VBIAS Supply voltage for the bias reference and control circuits. 14 VCC1 This pin is connected internally to the collector of the 1st stage RF device. To achieve specified perfor- mance, the layout of these pins should match the Recommended Land Pattern. 15 GND Ground connection 16 VCC2 This pin is connected internally to the collector of the 2nd stage RF device. To achieve specified perfor- mance, the layout of these pins should match the Recommended Land Pattern. 17 VCC3 This pin is connected internally to the collector of the 3rd stage RF device. To achieve specified perfor- mance, the layout of these pins should match the Recommended Land Pattern. 18 GND Ground connection 19 GND Ground connection 20 VTX Switch control for Tx mode 21 GND Ground connection 22 GND Ground connection 23 ANT RF Output is internally matched to 50 and DC blocked. 24 GND Ground connection Pkg Base GND Ground connection |
