SE7351L
3.3 - 3.8 GHz Front-End Transceiver
Applications
802.16, WiMAX Systems
Proprietary Broadband Wireless Access Systems
Wireless Local Loop
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.
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.
