Surface-mount RF transformer provides balanced-to-unbalanced transformation over a 650 to 4000 MHz frequency range in a 50 ohm system. The 1:1 impedance-ratio transformer uses Mini-Circuits AT224-1A case style with configuration G pinout and F17 tape-and-reel packaging information. Electrical ratings include 250 mW RF power, 30 mA DC current, and operation from -40°C to +85°C. Typical performance includes 0.5 dB mid-band referenced insertion loss, 0.5 dB amplitude unbalance, and 3 degree phase unbalance across the main operating band.
