GSM/DCS/PCS power amplifier
CGY2014TT
AC CHARACTERISTICS
V
DD
= 3.5 V; T
amb
= 25
°
C; measured on the Philips demoboard (see Fig.8).
Notes
1. The device is adjusted to provide nominal 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.
2. The power amplifier can be matched to PCS and or DCS/PCS operation through optimization of the matching circuit.
3. Isolation can be improved to
20 dBm (typical value) with a pin diode switched in the DCS output matching.
