Very High DC Current RF Choke ADCH-1220+ 50 5 to 1220 MHz The Big Deal Very wideband, 5 to 1220 MHz Maximum DC current handling capability of 200mA CASE STYLE: CD637 Excellent Insertion Loss, .2dB typical Good Return Loss, 25 dB typ. SMT Package Product Overview The ADCH-1220+ series of RF Chokes achieve very wide bandwidth from 5 up to 1220 MHz. The choke is wound with AWG32 wire, making the maximum continuous current 200mA DC. Excellent Insertion Loss, good VSWR (1.1:1 typ.), flatness and rugged construction make these models ideal solutions for rf-choke applications across a very wide frequency range. These units support a broad range of system and test applications. Key Features Feature Advantages Extremely wideband, 5 to 1220 MHz Ideal for an exceptionally wide variety of lab and system applications. Excellent Insertion Loss, .2 dB typ. Provides excellent signal transmission from input to output with consistent performance across entire range. across its entire frequency range. Good Return Loss, 25 dB typ. Efficient power utilization with minimal signal power reflected back to source 200mA DC continuous Ideal for DC injection applications requiring high current levels. Rugged Construction Withstands harsh environmental conditions for high reliability and long life of use. Notes A.
