The DBTC-20-4L+ from Mini-Circuits is a surface mount RF directional coupler designed for broadband applications.
This component operates across a wide frequency range of 20 MHz to 1000 MHz (1 GHz). It offers a nominal coupling factor of 20.4 ± 0.5 dB and a coupling flatness of ±0.8 dB across the specified frequency band. The mainline loss is rated at a maximum of 1.0 dB for frequencies up to 500 MHz, increasing to 1.3 dB up to 1 GHz. Directivity varies from a minimum of 13 dB at lower frequencies to 16 dB at higher frequencies. The device is rated for 1W of input power.
Designed for surface mounting, the DBTC-20-4L+ comes in a 5-SMD Module package. Its construction features all-welded assembly and leads optimized for better solderability. The coupler is also aqueous washable and protected by US patents.
Applications for this directional coupler include VHF/UHF receivers/transmitters and cellular systems.
