Advanced Control Components Surface-Mount 2-to-6 GHz Limiter Handles 10 W CW
NJ (June 14, 2010) – Advanced Control Components today introduced the Model ACLM-4805FM15
microwave limiter that combines high RF power handling ability of 10 W CW with a broad frequency range of 2 to
6 GHz and a compact surface-mount package.
The ACLM-4805FM15 is designed to keep the RF input signals experienced by low-noise amplifiers and front end
components of receivers to safe levels by attenuating signals above a specific threshold. They are essential
components in the receive chain of many communications and electronics warfare systems in which high signal levels
can degrade performance or destroy sensitive components. While there are many limiters available in the
marketplace, the ACLM-805FM15 is highly unusual in its ability to handle such high power over a broad frequency
range within the confines of a package with a very small footprint.
The limiter is rated to handle CW signal levels of 10 W and peak levels of 1 kW (1 µs pulse width, 0.1% duty
cycle) over a temperature range of -55o C to +85o C, or 20 W CW and 1 kW peak at 25o C. It has flat leakage of
+12.5 dBm with a 1 W input, VSWR of 1.4:1 or less, insertion loss of less than 1 dB, and third-order
intermodulation products of 23 dBm typical or better.
The ACLM-4805FM15 is housed in a ceramic
surface-mount package that can be hermetically sealed if specified by the customer. The limiter can also be
screened to meet the “hi-rel” requirements of MIL-PRF-38534G (MIL-STD-883), including internal visual, temperature
cycling, stabilization bake, constant acceleration, burn-in, and leak testing.
The ACLM-4805FM15 is the
first in a family of surface-mount limiters that Advanced Control Components will offer this year in bands from 20
MHz to 18 GHz. A model that covers 20 MHz to 2 GHz is currently available as well.
