QPB2040N RF Amplifier by Qorvo

The QPB2040N from Qorvo is a Solid-State Amplifier that operates in the Ka-Band from 18 to 40 GHz. It delivers a saturated output power of 50 dBm (100 W) with a power gain of 11 dB and has a power-added efficiency of 9.8%. This GaN amplifier is based on Qorvo’s patented and field-proven Spatium combining technology that provides unprecedented Solid-State Power Amplifier (SSPA) performance in a rugged, compact, and lightweight package. It is an excellent alternative to traveling wave tube amplifiers and is the ideal building block for various millimeter-wave subsystems with wide-ranging applications. The amplifier requires a DC supply of 18 V and consumes 54 A of current.

The QPB2040N has an integrated bias card, which allows for the convenience of operation, reducing electrical losses in the bias networks, and weight reduction over using a separate bias card. The bias card also provides individualized bias settings for each amplifier blade in the Spatium SSPA. It is available in a module that measures 3.94 x 2.91 x 4.04 inches with a 2.92 mm (female) input connector and WRD-180 double-ridged output waveguide interface.
