Highly Compact Embedded Duplexer Implementation for WiMAX Dual-band Front-end Module with Organic Package Substrate

In this paper, low cost and high performance duplexers are investigated for WiMAX front-end module with multi-layered organic package substrate. This dual band FEM includes a 2.5GHz power amplifier die with switch and has tiny PKG form factor. In addition to module size limitation, FEM requires higher gain and stringent attenuation characteristics specification. The embedded BPFs and duplexer w...

Integrated Aluminum Nitride Piezoelectric Microelectromechanical System for Radio Front Ends

This article summarizes the most recent technological developments in the realization of integrated aluminum nitride (AlN) piezoelectric microelectromechanical system (MEMS) for radio frequency (rf) front ends to be employed in next generation wireless communication devices. The AlN-based resonator and switch technologies are presented, their principle of operation explained, and some key exper...

Monolithic Integrated RF Front ends for Multi-GNSS receivers

The continuing expansion of available GNSS signals is an increasing challenge for receiver designers. New signals with expanded bandwidths are demanding greater sampling rates that require careful design of the receiver RF section to maximise performance tradeoffs. A high level of integration is required to preserve signal path integrity and minimise noise while keeping power consumption to a m...
