RF front ends, commonly abbreviated RF FE, are radio frequency (RF) subsystems found in certain space-constrained applications, usually used in wireless and cell applications. RF front ends are components often found in fields such as consumer electronics and automotive electronics. The most common components found in RF front ends are amplifiers, filters, switches, and antenna tuners. The SKY65378-11 is a high-performance RF front end module from Skyworks Solutions, Inc, which has found applications for antennas in UHF band.

The SKY65378-11 is specifically designed for applications that require low current, maximizing battery performance in portable consumer electronics while providing superior output power performance. It features a small size and low power consumption, making it perfect for portable applications such as Cordless Phones, 802.11 Based Access Points, and Zigbee Based Products. The SKY65378-11 is a high-performance RF front end module (LNA+PA) designed to cover the 315MHz, 433MHz, 868MHz, and 915MHz UHF bands.

The Skyworks SKY65378-11 RF front end module is designed to provide two switches and an impedance matching network to ensure optimal performance and flexibility for a variety of wireless applications. The module includes two integrated high-linearity amplifiers – one low noise amplifier (LNA) and one power amplifier (PA). Additionally, the integrated PA provides up to +31 dBm Linear Output Power (EIRP) and a noise figure of less than 1.5dB in the frequency range from 300 MHz to 915 MHz. The LNA features a noise figure of less than 0.5dB and a gain of more than 35 dB across the UHF band, providing low-noise performance.

A feature of the SKY65378-11 that allows it to operate at low power levels with good efficiency is the integrated impedance-matching network. This matching network ensures that impedance mismatch between the wireless devices and the module are minimized, allowing the RF signal to transmit efficiently. Additionally, two integrated SPDT switches provide further flexibility for the end user, allowing them to easily switch between different frequency bands or to connect and disconnect the antenna. This feature provides added protection for RF critical components.

The SKY65378-11 is ideal for antennas in UHF band, providing superior performance while maximizing battery life and portability. With its superior linearity, low power consumption, and integrated SPDT switches, the SKY65378-11 provides superior performance for antenna applications. Additionally, the integrated matching network ensures that impedance mismatch between the wireless device and the module is minimized, allowing the RF signal to transmit efficiently.
