Skyworks’ custom FEMs allow for significant size and

cost reduction. In addition, many of Skyworks’ FEMs

are designed to allow for “plug and play” functionality,

thus drastically reducing the design time for new

products. Customized FEMs can be created depending

on transceiver implementation requirements. Various

modules are being targeted at < 170, 410–470, 868–930,

and 2400–2500 MHz frequency bands. Figure 4 shows a

custom FEM block diagram.

Possibilities for Integration Include:

■

T/R Switches

■

Power Amplifiers

■

Low Noise Amplifiers (LNAs)

■

Mixers

■

Harmonic Filters
