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

TRF1122 offers  
a signal path to an off-chip  
band-pass filter. Specifications are provided  
assuming an in-band 2-dB insertion loss filter.

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.
