2.4 GHz Transmit/Receive Front-end Module with Integrated Low-Noise Amplifier

Skyworks SKY65352-11 is a high-efficiency Front-End Module (FEM). The device contains a 2400 to 2500 MHz high efficiency transmit path and a low-noise receive path.

The transmit path consists of a high efficiency Power Amplifier (PA) and harmonic filter. The receive path contains a low current Low-Noise Amplifier (LNA).

The transmit and receive paths are connected to a common Single-Pole, Double-Throw (SPDT) switch at both the input and output.

There is an internal balun that allows either the transmit input or the receive output to connect to a differential port.

The device is mounted in a 20-pin, 6 x 6 mm Multi-Chip Module (MCM) Surface-Mounted Technology (SMT) package, which allows for a highly manufacturable low-cost solution.

Please note: SKY65352-11 is being discontinued and is not recommended for new designs. The suggested replacement are SKY66108-11 and SE2438T
