The Amplifier Research DC7144A is a dual directional coupler designed with a frequency range of 0.7–4.2 GHz, handling up to 400 W CW and 4 kW peak power at 5% duty cycle with a 30 µs pulse. It offers a 40 dB ±1.3 dB coupling factor, 0.8 dB flatness, and directivity of 19 dB typical (15 dB minimum). With an insertion loss of just 0.4 dB and a 50-ohm impedance, the DC7144A ensures minimal signal degradation while maintaining a VSWR of 1.25:1 maximum.
Its dual directional design enables simultaneous monitoring of forward and reflected power, making it indispensable for RF susceptibility testing, amplifier overdrive protection, load safeguarding, and field control applications. It is ideally matched with AR 'S' series amplifiers and compatible instruments like the PM2003 power meter.
