QPB2731N

27.5 - 31 GHz Solid State Power Amplifier (SSPA)

An excellent alternative to traveling wave tube amplifiers, Qorvo's Spatium™ QPB2731N is a solid state, spatial combining amplifier with an operating range of 27.5 - 31 GHz while achieving greater than 49 dBm of instantaneous linear power. With its maximum performance in output power, gain, power added efficiency, and power flatness, this Spatium is the ideal building block for Satcom BUC's and other millimeter-wave subsystems with wide-ranging applications.

Qorvo's patented and field-proven Spatium combining technology provides unprecedented Solid-State Power Amplifier (SSPA) performance in a rugged, compact size and weight which reduces total cost of ownership compared to alternative technologies. This product offering combines Qorvo's market leadership in GaN technology and Ka-band MMIC design along with our high-count combining techniques for a best in class solution to power amplification.

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.
