RF LDMOS Wideband Integrated
Power Amplifiers
The A3I35D012WN wideband integrated circuit is designed for cellular base
station applications requiring very wide instantaneous bandwidth capability.
This circuit includes on--chip matching that makes it usable from 3200 to 4000
MHz. Its multi--stage structure is rated for 20 to 32 V operation and covers all
typical cellular base station modulation formats.

1. Second stage drains (VDD2A and VDD2B) must be tied together and powered by a single DC power supply.
2. Part internally input and output matched.
3. Measurements made with device in straight lead configuration before any lead forming operation is applied. Lead forming is used for gull
wing (GN) parts.
4. All data measured in fixture with device soldered to heatsink.
5. P3dB = Pavg + 7.0 dB where Pavg is the average output power measured using an unclipped W--CDMA single--carrier input signal where
output PAR is compressed to 7.0 dB @ 0.01% probability on CCDF.
