The Mini-Circuits VNA-28 is a wideband monolithic amplifier designed for high directivity applications. It operates across a frequency range of 0.5 to 2.5 GHz, providing a directivity of 14-21 dB. This amplifier is suitable for low voltage operation, requiring only 2.8 to 5V.
Fabricated using GaAs MESFET technology, the VNA-28 is enclosed in a compact 5x6 mm MCLP plastic package. This package style offers low inductance, repeatable transitions, and excellent thermal contact to the PCB. The design includes built-in DC blocks at the input and output, and a separate lead for DC, which helps reduce external component count and PCB size.
Its high directivity allows it to function as a low-cost isolator, minimizing interaction between pre and post-amplifier circuits. The VNA-28 is footprint compatible with the VNA-28 part, enabling its use as a replacement without PCB redesign. This makes it a versatile component for RF applications requiring signal amplification with minimal feedback.
