Low Insertion Loss Is A Major Gain For Mini RF Transformers

With their low insertion loss, the CX20xxL miniature RF transformers offer the signal integrity needed in sophisticated RF applications like set-top boxes, cable modems, wireless basestations, and wireless networking equipment. They come in various impedance ratios from 1:1 to 1:8. Featuring a typical insertion loss of less than 0.6 dB, the transformers provide operating frequencies from 0.05 to 1500 MHz. Reflow temperature rating for automated manufacturing processes is 235°C. Operating range is from - 40°C to 85°C. The devices use a low-profile design (0.110 in. maximum) with a footprint of 0.150 by 0.150 in. The CX20xxL series transformers cost $0.50 each.
