Product Description
2 1 0.80 TYP 1
The RF2163 is a linear, medium power, high efficiency amplifier IC designed specifically for low voltage operation. The device is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final RF amplifier in 2.5GHz spread-spectrum transmitters. The device is provided in a 16-pin leadless chip carrier with a backside ground and is self-contained with the exception of the output matching network and power supply feed line.

Pin 1 2 3 4 Function GND RF IN BIAS GND2 PWR SEN Description
Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. RF input. This input is AC coupled, so an external blocking capacitor is not required if this pin is connected to a DC path. Ground for second stage bias circuit. For best performance, keep traces physically short and connect immediately to ground plane. The PWR SEN and PWR REF pins can be used in conjunction with an external feedback path to provide an RF power control function for the RF2163. The power control function is based on sampling the RF drive to the final stage of the RF2163. Same as pin 4. This pin requires a regulated supply to maintain the correct bias current. Same as pin 6. Ground for first stage bias circuit. For best performance connect to ground with a 10nH inductor. Same as pin 1.

RF output and bias for the output stage. The power supply for the output transistor needs to be supplied to this pin. This can be done through a quarter-wave length microstrip line that is RF grounded at the other end, or through an RF inductor that supports the required DC currents. Same as pin 10. See pin 10. Same as pin 10. Not connected. Power supply pin for the bias circuits. External low frequency bypass capacitors should be connected if no other low frequency decoupling is nearby.
