The TRF1122IRTMR is an integrated RF mixer designed for up-conversion in 2.5-GHz radio applications, specifically operating within the frequency range of 2100 to 2700 MHz. It features a built-in IF amplifier, mixer, and local oscillator (LO) buffer amplifier, providing a gain of 20 dB and an output P-1 dB of +14 dBm, typical. The device includes a TTL-switched 16-dB attenuator for gain control and allows for power-down functionality via TTL control signals, making it suitable for power-sensitive applications. The TRF1122 also supports external image rejection or band-pass filtering, enhancing its performance in complex modulation schemes such as high-order QAM or OFDM. It operates with a positive supply voltage of 4.75 to 5.25 V and a negative supply voltage of -4.75 to -5.25 V, with a total supply current of approximately 185 mA. The device is packaged in a 32-pin VQFN format, suitable for various applications in the MDS, MMDS, and WCS bands.
