CAP Wireless Inc. (CAP), a supplier of high-performance microwave and RF amplifiers and amplifier-based subsystems, announced the CHPA0618-1 ultra-broadband power amplifier for broadband military platforms within the defense electronics and homeland security industries. The unit incorporates gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) technology into CAP’s patented Spatium™ broadband spatial combining architecture to achieve outstanding solid-state power levels across the amplifier’s extended 6 to 18 GHz frequency range. The CHPA0618-1 is ideally suited for wideband applications such as electronic counter measures (ECM), laboratory instrumentation, and electromagnetic compatability/electromagnetic interference (EMC/EMI) test, as well as narrower band applications like radar, microwave imaging and satellite communications.

“The CHPA0618-1 power amplifier delivers superior bandwidth and power through our Spatium technology and is a compact, affordable, reliable alternative to traveling wave tube amplifiers,” said Scott Behan, vice president of marketing at CAP Wireless. “This unit is uniquely positioned to meet the continually growing demand for components that can be implemented in highly specialized applications that require more bandwidth and efficiency, higher power, and are reliable and cost-effective to manufacture.”

In addition to extremely broad bandwidth and high power, the CHPA0618-1 amplifier’s multiple element architecture provides protection from single point failures and facilitates even, dispersive, three-dimensional (3D) heat dissipation.

Key features of the CHPA0618-1 include:

• Ultra-broad 6 to 18 GHz bandwidth

• 40 W typical saturated power

• Exceptional reliability and mean time between failures (MTBF)

• Graceful degradation (soft-fail) in the event of device failure

• Low voltage primary power

• Low intermodulation and harmonic distortion

• Flat gain without equalization

• Low noise figure

• Low phase noise and spurious

• Infinite load voltage standing wave ratio (VSWR) without damage

• No warm-up or turn-on delay

• Unlimited altitude
