APA Wireless (Booth 317) will introduce a new line of VCOs that operate independently of ground plane and load impedance at IMS 2011. These VCOs will drive a short circuit, open circuit, or anything in between regardless of ground plane over the industrial temperature range. They have excellent phase noise and linearity in the 4 to 7 GHz range. These devices provide exceptional performance in a variety of phase locked and free running applications.
