To avoid expensive and bulky couplers and reference circuitry, the tuner contains voltage and current sensors inserted before the antenna matching network. The sensed complex impedance generates 2-bit update controls for the tuning algorithm, which drives the MEMS-based tunable devices. The impedance sensing IC is designed to operate in the frequency range of 1.7–2.7 GHz and the clock frequency is 50 kHz.||Type of material:||Conference Publication||Publisher:||IEEE||Keywords:||Antenna tuner; Matching network; Impedance matching; Sensing element; Transmitter||Other versions:||http://www.rfic-ieee.org/||Language:||en||Status of Item:||Peer reviewed||Is part of:||Proceedings of IEEE Radio Frequency Integrated Circuits (RFIC) Symposium 2015||Conference Details:||IEEE Radio Frequency Integrated Circuits (RFIC) Symposium, Phoenix, Arizona, USA, 17 - 19 May 2015|
