The PMA2-123LN+ is a low-noise MMIC amplifier from Mini-Circuits, frequency range 50MHz-12GHz, noise figure 2.6dB, gain 16dB, in a DFN-6 package, suitable for wideband receiver front-ends.
The PMA2-123LN+ is an ultra-wideband low-noise MMIC amplifier from Mini-Circuits, operating from 0.5 GHz to 12 GHz in a 2 mm x 2 mm, 8-lead MCLP package. It combines a low noise figure of 2.2 dB at 2 GHz and 2.6 dB at 8 GHz with high output IP3 of +28 dBm and flat gain of 17.6 dB with plus or minus 2.0 dB variation across the full bandwidth. Operating from a single 5 V or 6 V supply at 51 mA (5 V) or 68 mA (6 V), this GaAs pHEMT amplifier is internally matched to 50 Ohms and requires no external matching components.
The PMA2-123LN+ employs an enhancement-mode GaAs pHEMT process to implement a two-stage low-noise amplifier. The input stage is optimized for minimum noise figure while the output stage provides high linearity and output power. The RF input and output are both internally matched to 50 Ohms across the full 0.5-12 GHz bandwidth. The device operates from a single positive supply voltage applied through the RF output pin (drain bias) via an external bias tee or RF choke. The MMIC topology provides simultaneous low noise figure and high IP3 by biasing the pHEMT devices at optimal drain current. The 2 x 2 mm MCLP package provides low-inductance ground connections through the bottom paddle, essential for stable microwave operation up to 12 GHz.

PMA2-123LN+ uses a 2x2mm 8-lead MCLP (QFN-style) package from Mini-Circuits with Pin 1 identified by a dot in the corner. The RF signal path is: Pin 3 = RF IN, Pin 6 = RF OUT + DC IN. All other pins (1,2,4,5,7,8) and the exposed paddle connect to GND. The RF OUT pin also serves as the DC supply input — an external RFC (radio frequency choke) or bias tee is required to inject 5V DC while blocking RF. Input and output are AC-coupled internally. The exposed paddle must be soldered to the PCB ground plane for both electrical ground return and thermal dissipation. Ground vias directly under the paddle improve RF performance at frequencies above 6GHz.

PMA2-123LN+ is a 0.5-12GHz MMIC LNA from Mini-Circuits in 2x2mm MCLP-8. The PMA2-153LN+ extends frequency to 15GHz with similar noise figure. PMA-545+ provides 50kHz-4GHz coverage with lower 0.75dB noise figure for sub-GHz applications. The PGA-103+ offers 0.05-6GHz with 23dB gain and higher +35dBm OIP3 for high-linearity receivers. The HMC519LC4 from ADI provides 24-34GHz low-noise amplification for millimeter-wave applications. All Mini-Circuits MCLP-8 amplifiers share the same 2x2mm footprint.
