two-stage

integrated

amplifier with active bias circuitry, and

50 Ω input/output matching inside the

package. With 3.3V supply voltage and

90mA nominal bias current, the Tx

path provides 27dB gain and +18dBm

linear output power, with extremely low

total EVM (<3%) for 64QAM/54Mbps

OFDM. Both gain and power are

readily measured at antenna port, with

switch insertion loss included.
