RF, Microwave, Millimetre wave Amplifier Modules

We offer power amplifier modules, bench top and rack mount solutions for EW, communications, broadcast, radar, and test applications. This includes EMC, narrow and broadband, low and high power amplifiers, together with linear amplifiers and custom solutions to meet specific parameters.

High Power Amplifiers

From HF to X-band, Castle can supply modular and rack mount amplifiers delivering up to hundreds of Kilowatts of pulse and c.w power using LDMOS and GaN on SiC technologies. Liquid cooled SSPA’s are also available that provide scalable pulse and CW up to X-band. Typical applications include EMC for radiated immunity testing, EW (jammers), radar and directed energy systems.

Small Signal Amplifier

Die and surface mount packaged gain blocks for Base Station, Broadband, CATV, Fibre Optic, Instrumentation, Wi-Fi, and WLAN applications with start frequencies as low as 10MHz up to 15GHz. Gain ranges from 12 to 21 dB and P1dB up to +27 dBm depending on technology.

Low Noise Amplifiers

Low noise amplifiers are board level and module solutions that provide low noise figure, extremely high gain, high linearity. They also provide broadband performance for communications, EW (SIGINT/ELINT), radar, direction finding, and network infrastructure up to 86 GHz

TMA - Tower Mount Amplifiers

The Tower Mounted Amplifier (TMA) amplifies weak uplink signals from mobile devices to provide improved balance between receive and transmit signals. TMAs remove interference, improving network performance and site coverage. Our range of TMAs cover all mobile bands, are suitable for single, multi-band or bypass application, AISG 2.0 compliant with support for single and multi-mode for maximum flexibility. An extensive portfolio of multi and single band versions with low noise figure and TX insertion loss these amplifiers provide market leading PIM performance for maximum throughput in LTE networks. Our designs offer small size and low weight for minimum tower loading and visual impact.

Bi-Directional Power Amplifiers

Solid state bidirectional amplifier (BDA) modules are ideal for extending the communication range of half-duplex transceivers. These amplifiers combine power efficiency and miniature, ruggedized packaging, making them ideal for size, weight, as well as power-constrained broadband telemetry, ISR, UAS and tactical communications systems.

SOA – Semiconductor Optical Amplifier

A Semiconductor Optical Amplifier (SOA) is essentially a laser diode (LD) with no feedback from its input and output ports and hence is also referred to as a Traveling-Wave Amplifier (TWA). Semiconductor Optical Amplifiers (SOAs) have proven to be versatile and multifunctional devices that are key building blocks for optical networks. We offer a range of devices covering peak wavelengths from 880 to 1550nm, with gain up to 30 dB and noise figure as low as 7 dB.

TIA – Transimpedance Amplifiers

Our range of optoelectronics products also includes transimpedance amplifiers (TIA) for line and client side 10G, 40G and 100G fibre optic receivers. The product portfolio includes linear TIAs for long haul coherent receivers and limiting TIAs for shorter range NRZ based receivers. These parts feature market leading gain, noise performance and power dissipation. They are available in die form for integration with photo-detectors in an optical sub-assembly.

Amplifier Applications:

Typical amplifier applications include:

  • Telecommunications
  • Satcom (Ku/Ka-bands)
  • VHF/UHF communications
  • Land/airborne/marine installations
  • Compliance testing
  • EW systems
  • Radar
  • Wi-Fi
