1787 to 1930 MHz High-Power RF Front-end Module

The SKY66104-11is a high-performance, highly integrated RF front-end module (FEM) designed for Digitally Enhanced Cordless Telecommunication (DECT) applications operating in the 1880 MHz to 1930 MHz frequency band, and extended applications for the 1787 MHz to 1792 MHz band.

The SKY66104-11 is designed for ease of use and maximum flexibility, with fully matched 50 Ω inputs and outputs, and digital controls compatible with 1.4 V to 3 V CMOS levels. An external Output Matching Network (OMN) between the PA output and the antenna switch provides ultimate flexibility in DECT applications.

A Normal Transmit Power (NTP) input is used to control power between –10 dBm and +25 dBm. NTP is a voltage-operated control with a very high input impedance (>100 kΩ) and a range of 0 V to 1.8 V.

The RF blocks operate over a wide supply voltage range from 3.0 V to 4.5 V, which allows the SKY66104-11 to be used in battery powered applications over a wide spectrum of the battery discharge curve.

The SKY66104-11 is packaged in a 24-pin, 4 x 4 mm Multi-Chip Module (MCM), which allows for a highly manufacturable low-cost solution.
