SSPA Transmitter

Given the reality of today's warfare, it is critical that the transmission range of active systems is fully optimized, maximizing radar jamming effectivity. Elbit Systems ISTAR and EW has developed a unique, compact and lightweight Solid State Phased Array (SSPA) transmitter covering all airborne, ground and naval platforms.

The high-performance system requires minimum power consumption – with less heat dissipation and low SWaP (Size, Weight and Power) – providing a transmitter that is technologically sophisticated as well as cost-effective. Through utilization of the Phased Array technique, Elisra's SSPA Transmitter provides a relatively narrow main beam and a high ERP (Effective Radiated Power).

Transmitter Description

The SSPA Transmitter utilizes numerous independent, active Solid State Transmit/Receive (T/R) modules that are multi-stage RF amplifiers. The bidirectional RF inputs are passed through a variable gain amplifier and variable phase shifter, which are time-shared between transmission and reception. The narrow beam steering is achieved by setting each T/R module with a phase shifting that depends on the direction of arrival and the wavelength of the threat. The T/R modules for the various frequency bands are based on GaAs and GaN technology.

Integration and Support

Elisra has the capability as well as extensive global experience in the integration of transmitters with all types of existing LPRF units – covering all airborne, ground and naval platforms. The transmitter can be customized to meet the customer’s needs.

The Company can also supply a full range of support tools as required.
