Miniature Ultra Flat Schottky
RLC Electronics’ miniature ultra-flat detectors
utilize a zero-bias Schottky design. The microwave power is coupled directly to the extremely
small components reducing package parasitics
and transition m i s m a t c h e s . This design re- sults in a very low VS WR and a flat, smooth out- put over a wide bandwidth. Op- tions available
or positive output, a choice of three output connectors and operation to 26. 5 or 40 GHz.
