This RF Cable Assembly is commonly used for Cellular (GSM/CDMA) radio modules which require the Hirose IPEX3/ W.FL connector. This assembly uses the .81mm RF coax cable, which has approx. 1dB per foot loss at 2.4Ghz. The SMA-female bulkhead connector does not have a center pin, and has a backing nut for bulkhead installations. The IPEX3/ W.FL connector is approx 1.5mm diameter, and offers a mated-height of 1.4mm, making it one of the most compact connectors for RF applications. Additional lengths are available in 100mm increments.
