The DB0402 from KYOCERA AVX are Thin-Film 90ยฐ Hybrid Couplers that operate from 3000 to 3400 MHz. These 3 dB couplers have an insertion loss of less than 0.8 dB and provide an isolation of more than 15 dB. They can handle an input power of up to 1 W and have a return loss of 15 dB. These couplers have an amplitude balance of 0.6 dB and a phase balance of 2ยฐ. They are based on thin-film multi-layer technology, which provides a miniature part with excellent high frequency performance and rugged construction for reliable automatic assembly.
The DB0402 are compatible with automatic soldering technologies such as reflow, wave soldering, vapor phase, and manual. These thin-film couplers also ensure low parasitic and better heat dissipation from the packages. They are available in 0402 sizes measuring 1.00 x 0.58 x 0.35 mm. These RoHS-compliant couplers are ideal for 4G/5G LTE, base stations, automotive, and industrial applications.
