Pasternack Enterprises, Inc., a leading manufacturer and supplier of RF, microwave and millimeter wave products, introduces a completely new line of broadband RF power combiners. The broad bandwidth of these new combiners makes them 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.

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

RF 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.

“With the addition of our new power combiners, we continue to expand our offering of solutions necessary to be our customers’ one-stop-shop for the complete component requirements of the RF system,” says Michael Rachlin, director of product management at Pasternack.

All of the new broadband, high power RF power combiners are in-stock and available to ship from Pasternack today. For detailed specs on these products, please visit
