SE7351L 40 pin, 6 mm x 6 mm QFN Samples SE7351L-T 40 pin, 6 mm x 6 mm QFN Tray SE7351L-AK3 - TDD Radio Application Board Product Description The SE7351L is a low noise, high linearity front-end transceiver for the 3.3 - 3.8 GHz band. The receiver provides a low noise down-conversion from RF to a 200 - 600 MHz intermediate frequency. 40 dB of gain control is available prior to the down-conversion for optimization of noise and linear ity. The gain control is divided between the variable gain LNA and a 3 bit digital attenuator with 4 dB step size. An off-chip filter between the LNA and mixer can be used for image rejection. The IF output has an off-chip matching network for flexible frequency planning and SAW filter selection. The transmitter up-converts to RF from a 200 - 600 MHz IF. The up-conversion mixer output is brought off chip to allow image band and LO suppression prior to final amplification. The tran smit attenuator has a three bit digital interface with 4 dB resolution and a total range of 25 dB.
