venture business credited for the development of polar modulation
techniques for use in wireless transmitter applications.
It said the closed-loop polar modulation
transmitter design used, helps reduce complexity of design and offers an improvement on the open-loop polar designs.
Combined with size reduction and an increase in overall performance, the RF3178 is designed to support polar modulation
in combination with the POLARIS 2 Radio Module solution.
This generation includes the quad-band RF3158 (GSM/GPRS/EDGE), optimized for linear EDGE using either direct I & Q modulators or small signal polar modulation
, and the quad-band RF3166 (GSM/GPRS), optimized for GSM/GPRS Class 12.
The SKY77519 transmit-receive (Tx-RX) FEM for quad-band GSM/GPRS/EDGE-single band WCDMA antenna switch support contains a very low profile and EDGE polar modulation
This PA represents greater than 30 percent size reduction and is optimized for linear EDGE using either direct I & Q modulators or small-signal polar modulation
Originally introduced in May 2007, the SEQ7400 is based on the company's patented FullSpectra[TM] architecture, which includes the only transmitter in the industry to use polar modulation
in all modes.
Originally introduced in May 2007, the SEQ7400 is based on the company's patented FullSpectra(tm) architecture, which includes the only transmitter in the industry to use polar modulation
in all modes.
This FEM supports Class 12 GPRS multi-slot operation and EDGE polar modulation
, while also providing an antenna switch through port to support WCDMA Band 1 or 2.
With the SEQ7400, Sequoia Communications remains the only company demonstrating working polar modulation
