Patent ID: 8681748

Claim:
A WiFi/WiMAX (WiWi) device, comprising: a WiMAX transceiver; and a WiFi transceiver; wherein the WiMAX transceiver comprises: a WiMAX radio frequency (RF) integrated circuit (RFIC); and a first RF analog front end, coupled to the WiMAX RFIC; wherein the first RF analog front end comprises: a WiMAX transmit path, including a first WiMAX band-pass filter (BPF) and a first power amplifier (PA), the first WiMAX BPF placed before the first PA in the WiMAX transmit path, wherein the first WiMAX BPF is configured to band-pass, filter WiMAX transmissions from the WiMAX RFIC to reduce emissions outside of a WiMAX frequency band contained in the WiMAX transmissions, thus protecting the WiFi transceiver from said emissions; and first and second WiMAX receive paths, each including a first low-noise amplifier (LNA) and a second WiMAX BPF, the second WiMAX BPF placed before the first LNA in the first and second WiMAX receive paths.
