Frequently asked questions

We supply the complete Altum RF portfolio, including GaAs and GaN MMIC power amplifiers, low noise amplifiers, driver amplifiers, distributed amplifiers and switches operating from X-band through to D-band (over 100 GHz) for satcom, telecommunications, radar, test and measurement, aerospace and defence applications.

Yes. Emerges is an AS9120B-certified and IAQG-registered authorised distributor supplying genuine Altum RF MMIC amplifiers and millimetre wave semiconductors, backed by full traceability and manufacturer warranty support.

GaAs (Gallium Arsenide) MMIC amplifiers typically deliver low noise figure and high gain at moderate power levels, ideal for receive chains and low noise applications. GaN (Gallium Nitride) MMIC amplifiers deliver significantly higher output power density, wider bandwidth and better thermal performance, making them ideal for high power transmit applications including radar transmit modules and SATCOM ground terminals.

Altum RF MMIC products cover the full RF to millimetre wave spectrum from X-band through to D-band (over 100 GHz). The portfolio includes dedicated product families for X-band, Ku-band, Ka-band, Q-band, V-band, E-band and W-band, supporting applications from radar through to millimetre wave wireless backhaul and SATCOM.
