Mini-Circuits has introduced the PMA1-14LV+, a wideband MMIC low-noise amplifier designed for high-dynamic-range receiver front ends operating from 0.05 to 10 GHz. The pHEMT-based surface-mount device is aimed at RF systems that require low noise, strong linearity, and compact integration without the complexity of external matching.
The MMIC amplifier provides a typical gain of 21.9 dB with a flat response across the operating band. It provides a noise figure of 0.8 dB at 2 GHz, 1.0 dB at 4 GHz, and rising to 1.8 dB at 10 GHz. This amplifier maintains linearity, with an output third-order intercept point (OIP3) of +28.4 dBm at 4 GHz, while output power at 1 dB compression reaches +20.4 dBm at the same frequency. It provides isolation across the full band of 26.7 dB, supporting stable front-end operation in crowded spectral environments.
The PMA1-14LV+ is based on a single +5 V supply, with a typical operating current of 60 mA. This device is internally matched to 50 ohms at both input and output and can handle the RF input power of 25 dBm. This wideband amplifier is available as a surface-mount device in a 6-lead QFN-style package measuring 1.5 × 1.5 mm, with good thermal conductivity to the PCB.
The amplifier is ideal for applications that include test and measurement equipment, backhaul radio systems, satellite communications, radar and electronic warfare receivers, and 5G wireless infrastructure, where wide bandwidth, low noise, and high linearity are essential for maintaining receiver performance in increasingly congested RF environments.
