RF Glossary: G | Terms Starting with G

Gain — The ratio of output power to input power in an amplifier or antenna, typically expressed in dB. In antennas, gain includes the effect of directivity and efficiency.

Gain Flatness — The variation in gain across a specified frequency band, typically expressed as peak-to-peak variation in dB.

GaAs (Gallium Arsenide) — A III-V compound semiconductor material used in high-frequency transistors, MMICs, and optoelectronics due to its high electron mobility.

GaN (Gallium Nitride) — A wide-bandgap semiconductor material used in high-power, high-frequency amplifiers and switches due to its high breakdown voltage and power density.

Group Delay — The rate of change of transmission phase with respect to frequency, representing the time delay experienced by the envelope of a signal.

Guard Band — An unused frequency band between two adjacent communication channels that prevents mutual interference.

Gunn Diode — A transferred-electron device that generates microwave oscillations when biased above a threshold voltage, used as a compact microwave source.
