Mini-Circuits

Mini-Circuits, headquartered in Brooklyn, New York, supplies RF and microwave components — mixers, splitters, filters and MMIC amplifiers — for communications, test and industrial equipment. The profiles here cover three MMIC amplifier codes. The GVA-63+ is an InGaP HBT gain block in SOT-89 covering 0.01 to 6 GHz with about 21 dB of gain, aimed at IF and driver stages. The PGA-103+ is an E-PHEMT low-noise amplifier spanning 0.05 to 4 GHz with a 0.6 dB noise figure at 1 GHz, a common choice for receiver front ends. The PMA3-14LN+ extends the low-noise role to 10 GHz in a 3x3 mm QFN with a 1.0 dB noise figure at 2 GHz. The trailing plus sign is part of the ordering code and denotes the RoHS-compliant build — quote it in full. Gain, noise figure and output power all move with frequency, so confirm the figures at your operating band before committing a design.

Sourcing notes for Mini-Circuits parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
