The LM202802-M-C-300 from MACOM is a passive two-stage power limiter which operates from 2 to 8 GHz. It can handle RF CW incident power of up to 45 dBm and RF peak incident power levels of up to 53 dBm (1 µs RF pulse width, 0.1% duty cycle). The limiter has a flat leakage power of 20 dBm with an insertion loss of 1.4 dB, low noise figure and a high isolation. The design incorporates a silicon NIP coarse limiter diode and a silicon PIN clean-up stage diode integrated onto a ceramic substrate. It is available in a surface mount package that measures 8 mm L x 5 mm W x 2.5 mm H.
