Philips Semiconductors

Preliminary specification

DCS/PCS 2 W power amplifier

CGY2021G

AC CHARACTERISTICS

Measured and guaranteed on CGY2021G evaluation board.

Notes

1. Including the 82

Ω resistor connected in parallel at the power amplifier input on the evaluation board.

2. The device is adjusted to provide nominal value of load power into a 50

Ω load. The device is switched off and a 6 : 1

load replaces the 50

Ω load. The device is switched on and the phase of the 6 : 1 load is varied

360 electrical degrees during a 60 seconds test period.
