iFEM Integrates BAW Technology

Qorvo’s QPF7200 iFEM integrates a 2.4GHz PA, bypassable Tx BAW filter, LNA with bypass function and Rx coexistence BAW filterRFMW, Ltd. announces design and sales support for an integrated Front End Module (iFEM) designed for Wi-Fi applications. Qorvo’s QPF7200 integrates a 2.4GHz power amplifier, bypassable transmit BAW filter, LNA with bypass function and receive coexistence BAW filter into a single module measuring 8 x 5.5mm. Integration of key Tx/Rx functions reduces part count and shrinks PC board designs. The QPF7200 reduces BOM count by >25 components versus discrete designs yet provides +25dBm while maintaining spectral compliance. Gain is measured at 36dB which reduces the power required from an SoC transceiver chip. Receive gain is 12dB with low noise figure of 2dB for increased signal sensitivity. Band edge filters and coexistence filters provide improved performance by eliminating unwanted signal intrusion. 5GHz rejection of the receive path is 45dB.
