RF Power Combiners

Pasternack’s broadband, high power RF combiners are the perfect complement to systems using components such as power amplifiers, antenna feeds, attenuators and switches. A special area of usage for these power combiners is in combining individual power amplifiers together into a large power block in an amplifier system. Power combiners are devices that combine or sum a number of RF input signals to a common output, while maintaining the characteristic impedance of the inputs. As systems become more complex, choosing how best to combine two or more RF signals has become a far more difficult question to answer, especially when high power and wide bandwidth are involved. Pasternack’s RF combiners offer low loss and low VSWR while providing competitive port-to-port isolation through the use of high power resistive components. These RF signal combiners are designed to be screw-down mounted to a heatsink.

Our RF power combiners are offered in the popular 2-way and 4-way configurations and deliver high power up to 600 Watts and operate over a broad temperature range between 55°C to 85°C, expanding the versatility of this product offering to a wide range of military and commercial applications. These broadband RF combiners offer frequency ranges from 20 MHz to 6 GHz, low insertion loss from 0.35 dB to 1 dB and low VSWR up to 1.30:1. Other features of the power combiners include excellent amplitude and phase balance, high power handling, good isolation levels and rugged packaging.
