SE7351L 3.3 - 3.8 GHz Front-End Transceiver Applications 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 linearity. 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. 802.16, WiMAX Systems Proprietary Broadband Wireless Access Systems Wireless Local Loop Features Low Noise, High Linearity Receiver Receive gain = 20 dB Receive NF = 3.0 dB (whole chain, including filter) Receive IP1dB = -4 dBm Transmit gain = 30 dB Transmit gain range = 25 dB Transmit output P1dB = 11 dBm 3.3 or 5 V operation Lead Free and RoHS Compliant Part of SiGe’s chipset solution for 3.3 - 3.8 GHz BWA systems Lead Free, RoHS compliant, 6 x 6 mm, MSL3 Package 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 transmit attenuator has a three bit digital interface with 4 dB resolution and a total range of 25 dB.
