Surface Mount RF Transformer 100 to 50Ω TRS2-252+ 4 to 2500 MHz The Big Deal • Very wide bandwidth, 4 to 2500 MHz • Low, flat insertion loss, 0.98-1.71 dB • Good return loss, 20 dB typ. at 1 dB CASE STYLE: AT577 Product Overview The TRS2-252+ is a mini unbalanced-to-unbalanced, very wide bandwidth transformer measuring only 0.2” on all sides, with a flat top for pick and place compatibility. The rugged, wire-welded, rectangular-core design is RoHS-compliant, with an open style, aqueous washable, ceramic case and gold-plated terminals. Feature Advantages Very wide bandwidth 4-2500 MHz frequency range for use in cable or broadcast TV & radio, GPS, cellular communications, avionics, and radar implementations Very good, flat insertion loss Insertion loss flatness ±0.35 across operating range maintains gain flatness when used as a step-up or step-down transformer in amplifier or filter circuitry Good, flat return loss 22 ±4.7 dB return loss at 1 dB provides excellent matching for 50/100 Ω circuits Mini-Circuits ® ISO 9001 ISO 14001 AS 9100 CERTIFIED P.O.
