LA7 / SMLA7
Limiting Amplifier
50 to 500 MHz
Features
• SYMMETRICAL CLIPPING
GOOD EVEN-ORDER SUPPRESSION
• HIGH OUTPUT LEVEL: +11.5 dBm (TYP.)
• HIGH THIRD-ORDER IP: +28 dBm (TYP.)
• FAST PULSE RECOVERY TIME: < 50 NSEC (TYP.)
Description
The LA7 limiting amplifier is a discrete hybrid design, which
uses thin film manufacturing processes for accurate
performance and high reliability.
This design uses a Schottky diode limiter circuit at the input,
and a single stage bipolar transistor feedback amplifier at the
output. An RF choke is used for DC power supply decoupling.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available.
