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.

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

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.
