Limiting Amplifiers & Limiters

When your circuit design requires amplitude compression, Spectrum Control delivers the RF limiting function with its line of RF limiting amplifiers. These amplifiers are useful for protecting subsequent components from input overdrive and removing amplitude modulation from FM signals.

Features

GMIC Limiters
  • Utilising APITech's GMIC (Glass Microwave Integrated Circuit) Technology, integration applications can benefit from both small feature size and high performance.
  • High reliability S-band 'Drop-in' limiter module features a weight and space saving design.
  • High power with minimum 50dB isolation.
High Input Power Ranges
  • APITech offers receiver protection for frequencies from 5 MHz to 1000 MHz.
  • With input power levels up to +26 dBm, use as a clean-up limiter with higher power limiters or stand-alone for lower power requirements.
Hermetic Kovar Packaging
  • Surface mount kovar packaging offers superior protection against severe environmental conditions.
Custom Solutions
  • We offer slightly modified standard units.
  • Fully customized designs are available upon request.
Drop-in Replacements
  • We cross most major manufacturer's standard catalog parts.
  • We also improve performance over their existing designs.
Adjustable Gain Controlled Amps
  • Our AGC designs offer adjustable gain control from 10-500 MHz with up to 45 dB in gain.
