| Description: The CP1 is an ideal companion to Elecraft's 2T-Gen two-tone test generator. It is a dual directional coupler that provides high directivity, can be internally or externally terminated, and can be constructed with a coupling loss of either 20 or 30 dB. It can be used to sample a transmitter's forward power and reflected power output. For two-tone measurements, the forward power port can be connected to an oscilloscope or station monitor for display of the transmit envelope. The unit is quite versatile; for example, it can be used with a diode detector to create a 25-W or 250-W SWR bridge. For more advanced applications, the CP1 can be used with a spectrum analyzer and tracking generator to sweep the return loss (SWR) of an antenna or other device in real time. The unit operates over a 1 MHz to 30 MHz frequency range. When built as a 30-dB coupler, it can handle up to 250 watts. When built for 20 dB coupling, maximum power is 25 watts. In either case, coupling loss is accurate to +/- 0.25 dB, and directivity is approximately 30 dB. | |||

Elecraft CP1 Directional Coupler
The CP1 is an ideal companion to Elecraft's 2T-Gen two-tone test generator.
It is a dual directional coupler that provides high directivity, can be internally
or externally terminated, and can be constructed with a coupling loss of
either 20 or 30 dB. It can be used to sample a transmitter's forward power
and reflected power output. For two-tone measurements, the forward power
port can be connected to an oscilloscope or station monitor for display of the
transmit envelope.
The unit is quite versatile; for example, it can be used with a diode detector
to create a 25-W or 250-W SWR bridge. For more advanced applications, the
CP1 can be used with a spectrum analyzer and tracking generator to sweep
the return loss (SWR) of an antenna or other device in real time.
The unit operates over a 1 MHz to 30 MHz frequency range. When built as a
30-dB coupler, it can handle up to 250 watts. When built for 20 dB coupling,
maximum power is 25 watts. In either case, coupling loss is accurate to +/-
0.25 dB, and directivity is approximately 30 dB.
