General Notes:
GENERAL SPECIFICATIONS
1. The CYM-R series of directional couplers consists of three port connectorized
devices utilizing special stripline technology for very high directivity over very wide
bandwidths.
Impedance:
50 W nom.
2. Although the CYM-13R-9G is fully specified down to 170 MHz, it is usable down to
100 MHz with a higher coupling. Units covering up to 20 GHz are available on special
order.
3. This series is ideally suited for precise measurement of forward or reflected power
in general purpose ATE systems as well as in EW and similar wideband systems where
high directivity is essential.
4. These units comply with MIL-C-15370 and can be supplied screened for compliance
with additional specifications you designate for military and aerospace applications
requiring the highest reliability.
Coupled ‘‘Loss’’ at 13 dB: 0.22 dB
Peak Power:
3 kW max.
CW Input Power (Forward): 25 Watts max.
CW Reflected Power:
5 Watts max.
Operating Temperature:
-- 55° to +85°C
