MegiQ 4 GHz PC-based VNA

The MegiQ VNA0440 from Emona Instruments is an affordable and compact USB-driven, fully bidirectional two-port VNA that enables detailed impedance measurements of antennas, components and circuits over a range of 400 to 4000 MHz, ie, all popular communication bands for GSM-LTE, GPS, ISM, Wi-Fi, Dect and so on.

An extra generator output is useful for characterising 3-port devices such as splitters and hybrids. The internal, programmable bias generator with bias tees enables fully automatic parametric measurements of, for example, amplifier and varactor/PIN circuits.

The UFL kit enables measurement of circuits on micro-PCBs, such as baluns, antennas and amplifiers. Other kits are available: WFL, SMA and balanced, including calibration tools. The PC software provides intuitive control, extensive graphing, data export and reporting. Measurements and set-ups can be stored in sessions for easy ‘Retrace-and-Compare’. The handy ‘Click-and-Match’ calculates and simulates matching circuits.
