General Description
TGA2703-SM is a linear amplifier
operating
for
802.16
broadband
wireless applications in 3.3 to 3.8 GHz
frequency band. The PA delivers 24 dB
of small-signal gain, 30dBm P1dB and
40 dBc IMR3 at 21 dBm output power
per tone from a single +6V power
supply. It has 2.5% EVM at 22 dBm
output power.
The TGA2703
incorporates a 13 dB step attenuator
function and a power sampling port.
The 50 ohm device requires minimum
external components for operation, and
is packaged in a low-cost, surface
mount 5x5 QFN style package.
Lead-Free & RoHS compliant.
Demo boards are available.
