Directional Couplers
- Frequencies from 10 KHz to 18 GHz
- All Coupling Values
- Narrow Bands to Multi-Decade Bands
- Lumped or Distributed Element Construction
- Low Loss, Low VSWR
- Small, Compact Packages

UMCC offers a wide selection of unidirectional and bi-directional couplers covering frequencies from 10 KHz to 18 GHz. These couplers are available from narrow bands to multi decade bandwidths with all coupling levels of 6, 10, 16, 20, and 30dB values.  Many couplers are available with standard connectors (SMA, BNC, N, others). 

UMCC low frequency dividers (10 KHz to about 1 GHz) are of lumped-element construction, where ferrite elements are used in coupler circuitry.  UMCC low frequency couplers cover mainly wide bands of two to three decades.

UMCC high frequency couplers (0.5 to 18 GHz) are of distributed element construction.  Stripline transmission lines are etched monolithically on a Teflon base medium creating impedance transformation and the coupling function.  UMCC high frequency dividers are offered from narrow bands of one octave to multi octave bandwidths.

UMCC offers a limited series of a very unique semi lumped element couplers in frequency range of 20 MHz to 3 GHz.  These series cover a wide bandwidth of two to three decades.  Their construction is a combination of lumped-element ferrite component with distributed element transmission lines.
