Description
The LM202802-M-C-300 Surface Mount PIN Diode
Limiter Module is a surface mount, passive 2-stage
power limiter. It is manufactured using a proven
hybrid manufacturing process incorporating silicon
NIP and PIN diodes integrated onto a ceramic
substrate. This low profile, surface mount
component offers superior small and large signal
performance. This product is designed to minimize
small signal insertion loss for very low receiver noise
figure and high isolation for low flat leakage power
for effective receiver protection from 2 - 8 GHz.
The design incorporates a silicon NIP coarse limiter
diode and a silicon PIN clean-up stage diode to
provide broadband microwave performance from
2 - 8 GHz. The NIP and PIN diode configuration
eliminates the need to include an RF choke to
complete the DC bias return path. The very low
thermal resistance (NIP diode: <20ºC/W, PIN diode:
<90ºC/W, junction to the bottom surface of the
package) enables the limiter to safely and reliably
handle RF CW incident power levels of 45 dBm and
RF peak incident power levels of 53 dBm (1 μs RF
pulse width, 0.1% duty cycle). The low PIN and NIP
diodes’ series resistances (<1.5 Ω) provide low flat
leakage power (<22 dBm) and the thin I layer of the
output stage provides low spike leakage energy
(<0.5 Ergs) for superior LNA protection. No external
control signals are required.
