To keep the RF input signals experienced by low-noise amplifiers (LNAs) and receiver frontend components to safe levels, a new limiter is designed to attenuate signals above a specific threshold. Dubbed model ACLM-4805FM15, this microwave limiter covers 2 to 6 GHz. It is rated to handle continuous-wave (CW) signal levels of 10 W and peak levels of 1 kW (1 s pulse width, 0.1 percent duty cycle) over a temperature range of -55 to +85C or 20 W CW and 1 kW peak at +25C. The limiter has leakage of +12.5 dBm with a 1-W input and VSWR of 1.40:1 or less. It exhibits insertion loss of less than 1 dB while third-order intermodulation products are typically +23 dBm or better. The ACLM-4805FM15 is housed in a ceramic surface-mount package that can be hermetically sealed if specified by the customer.
