Complete microwave systems require substantial signal processing between input/s and antennas and this applies to radio systems, EW (including jamming) and radars. Immediately “behind” the antenna, on the transmission side there is always the need for a microwave power amplifier and the technologies required are nowadays almost universally solid-state i.e. semiconductor based. Until quite recently devices such as travelling-wave tubes (TWTs) often fulfilled this role but semiconductors are now dominating. Occasionally combinations of solid-state and TWTs are used to form a TWTA: a TWT driven by a solid-state PA. This report is entirely concerned with microwave SSPAs (MWSSPAs). Several parameters characterize an SSPA but the RF output power is particularly significant – it ranges from a few Watts (30-40 dBm) through to several kW. The output is either continuous-wave (CW) especially for EW or pulsed for many radars, typically with 10:1 ‘duty cycles’.
For present purposes in this report SSPAs are characterized into the following categories:
Medium-power amplifiers (MPAs);
High-power amplifiers (HPAs), and:
Very high power amplifiers (VHPAs).
For many military applications microwave bands including the L, S and X-bands are particularly important and SSPAs covering each of these bands are frequently specified. In this report monetary values of total addressable markets are presented (TAMs in US$) for historical year 2023 and for each subsequent year up to and including year 2030. These TAMs are segmented by sales into EW and radar applications and annual growth rates are provided.
