Description
An excellent alternative to traveling wave tube amplifiers,
Qorvo’s Spatium™ QPB0220N is a solid state, spatial
combining amplifier with an operating range of 2–18 GHz.
With its maximum performance in output power, gain,
power added efficiency, and frequency range, this Spatium
is the ideal building block for microwave 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 MMIC
design along with our high-count combining techniques for
a best in class solution to power amplification.
The QPB0220N 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
as well as drain pulsing up to 1 MHz PRF for superior power
savings and noise performance.
