Along with a host of other products debuting at IMS, Qorvo will be in Booth 935 with three new solid-state power amplifiers (SSPAs) for commercial and defense communications, radar, electronic-warfare (EW), and other wideband applications. The QPB2040N, QPB0220N, and QPB0618N, part of Qorvo's Spatium SSPA portfolio, provide an excellent alternative to traveling-wave-tube amplifiers (TWTAs).
Qorvo's QPB2040N SSPA operates from 18 to 40 GHz, spanning the K and Ka bands. With its wideband output power performance (100 W CW) in a compact size of less than 50 in.3, it's a suitable building block for various mmWave subsystems in wide-ranging applications. The QPB2040N is equipped with an integrated bias card, which reduces electrical losses in the bias networks and provides individualized bias settings for each amplifier blade in the SSPA, as well as drain pulsing for superior power savings and noise performance.
The new QPB0220N and QPB0618N SSPAs are solid-state, spatial combining amplifiers operating in the S, C, X, and Ku bands. With their optimized output power, gain, and power-added efficiency over their respective frequency ranges, these Spatium SSPAs further expand the company's family of products to support a growing industry need for modular, scalable, reliable, and fully tested products.
Over the wide frequency bands and over temperature at CW conditions, Spatium SSPAs are claimed to provide higher output power and efficiency than any other known solid-state products in the industry. Compared to TWTAs, the QPB0220N covers a wider frequency band than any other available product, said Qorvo.
According to the company, its Spatium SSPAs provide a more reliable, easier-to-use solution with reduced size, weight, and total cost of ownership, as compared to solutions based on their closest TWTA counterparts.
