Innovative Alternative to Traveling Wave Tube Amplifiers
RFMW announces design and sales support for a high frequency, high power amplifier from Qorvo. Qorvo’s Spatium™ QPB2731N is a solid state, spatial-combining amplifier with an operating range of 27 to 31 GHz. With >49 dBm of instantaneous linear power, this amplifier is the ideal building block for Satcom BUC’s and other millimeter-wave subsystems with wide-ranging applications. Using patented and field-proven Spatium combining technology, the QPB2731N provides unprecedented performance in a rugged, compact size and weight which reduces total cost of ownership compared to alternative technologies. The QPB2731N is equipped with an integrated bias card, which allows for convenience of operation, reducing electrical losses in the bias networks, and weight reduction over using a separate bias card. It provides individualized bias settings for each amplifier blade in the Spatium SSPA.
