MPD Fully Functioning During the Covid-19 Emergency

We just thought we’d let all of you know that it is business as usual at Octagon Communications and MPD. All necessary precautions have been taken, and, as several of our staffers already work remotely, the office is open for business until we are told otherwise.

The June issue of MPD will arrive on schedule, and of course our website and the digital edition will continue to be available.

Feel free to contact any of us with questions or concerns!

We hope that you and your families are safe and healthy.

The Design of an L-band 125W GaN PA


Plextek RFI has published a new white paper on its website, entitled ‘The Design of an L-band 125W GaN PA‘.

The white paper describes the design and evaluation of a single stage 125W L-Band GaN Power Amplifier using a low-cost packaged transistor. The amplifier is optimized for the 0.96 to 1.215 GHz band with a typical band center gain of 20dB and output power at P-3dB of +51dBm (125W) at a PAE (for the connectorised amplifier) of > 70%. The design is based on a commercially available discrete 0.25μm GaN transistor, housed in a metal-based ceramic package (the QPD1008 from Qorvo).
