Broadband coaxial limiters suppress even-order harmonics under hard limiting conditions
Common applications for these RF limiters include electronic warfare, instrumentation, fiber optic communication systems, military communications, radar, SATCOM, point-to-point radio, telecom, data links and R&D.
The company’s latest release of high power limiters consists of seven unique designs that provide low leakage power to sensitive control components in the receiver chain while offering good suppression of even-order harmonics under hard limiting. These RF limiters operate over a very broad frequency range in bands from 0.5 GHz to 40 GHz and also provide low leakage power circuit protection of 10 to 15 dBm. This latest selection of coaxial limiters exhibits high CW power handling up to 100 W peak power and fast recovery time of 10 to 100 nanoseconds.
The high power, broadband limiters help stabilize generator outputs, provide constant amplitude signals in phase sensitive systems and reduce amplitude variation in frequency modulation (FM) systems. The 50 Ohm hybrid designs incorporate complete limiting diode circuitry and do not require any external matching components. These microwave limiters offer a guaranteed operating temperature range of -54° C to +85° C and are constructed with high-rel, ruggedized packages that are designed to meet MIL-STD-202 environmental conditions for humidity, shock, vibration, altitude and temperature cycle.
