MMIC Power Amplifier Handles 10 MHz to 22 GHz
The PMA5-223+, a gallium-arsenide (GaAs) pHEMT distributed MMIC power amplifier covering 10 MHz to 22 GHz, is Mini-Circuits' widest-bandwidth MMIC power amplifier to date. The device combines more than three decades of frequency coverage with +33-dBm (2 W) typical saturated output power and 15.5-dB typical gain, addressing applications that include wideband test instrumentation, satellite communications, radar, and electronic-warfare systems.
Made for broadband signal chains demanding high power and low distortion, the PMA5-223+ has a typical output third-order intercept point (OIP3) of +43 dBm at 10 GHz, measured at +20-dBm output power per tone. Offering bandwidth, power, and linearity for systems operating across multiple frequency bands, the amplifier has internal 50-Ω input and output matching.
It comes in a 5- × 5-mm, 32-lead QFN-style surface-mount package. A bare-die version is also available.
