| 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.) Rev. V2 Product Image 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. Ordering Information Part Number LA7 SMLA7 CLA7 ** Package TO-8 Surface Mount SMA Connectorized ** The connectorized version is not RoHs compliant.
