The TRF1122 up-converts a UHF IF signal to an RF

signal in the 2100-MHz to 2700-MHz range for

2.5-GHz radio applications. The TRF1122 has 20 dB

of gain and an output P-1 dB of +14 dBm, typical. A

TTL compatible, 1-bit 16-dB switched attenuator is

provided for gain control and the IF and RF

amplifiers can be shut off via a TTL control signal for

power critical or TDD applications. In order to provide

system requirements for LO/spurious rejection, the

RF Amplifier

The TRF1122 is designed to complete the second

up-conversion in Texas Instruments complete

2.5-GHz chip set. The linear nature of the

up-converter makes it ideal for complex modulations

schemes such as high order QAM or OFDM.
