RF Parts Australia provides The RF7178 and RF7177 front end modules released by RFMD
RFMD has released the RF7178, which is a front end module that integrates a quad-band, class 12-compliant GSM/GPRS power amplifier, a pHEMT antenna switch and SAW filters. The RF7178 offers full quad-band transmit performance (GSM850/EGSM900/DCS1800/PCS1900) and four dedicated receive ports (150Ω impedance) in a compact single-placement package.
The integrated transmit module simplifies the phone design by eliminating the need for complicated control loop design, output RF spectrum, (ORFS) optimisation, harmonic filtering and component matching. In order to deliver a low-loss, high-efficiency front-end solution without requiring additional matching components, both transmit and receive paths are performance optimised.
They have also released the RF7177, a dual-band (EGSM900/DCS1800) front end module that is pin-to-pin compatible with the RF7178 and features a similar feature integrating the pHEMT antenna switch and SAW filters. When RF7178 and RF7177 are combined, they provide a scalable platform solution for handset manufacturers who seek advanced levels of integration, streamlined inventory management and minimal deployment of valuable RF design resources. These modules reduce assembly costs, improve line yields and lower purchasing and managing inventory costs.
