Plessey Semiconductors has introduced the PS13201 Logarithmic/Limiting Amplifier, a pin-for-pin, drop-in compatible replacement for the original Plessey SL3522 log amp.
The PS13201 Log Amp is a monolithic seven stage successive detection logarithmic amplifier IC for use in the 100MHz to 500MHz frequency range.
It features an on-chip video amplifier with provision for external adjustment of log slope and offset. It also features a balanced RF output. The PS13201 operates from supplies of ±5V. The PS13201 is specified across the military temperature range of -55°C to + 125°C.

• 0dBm RF Limiting Output
• 60dBm Limiting Range
• 2V Video Output Range
• Low Power (Typ. 1W)
• Temperature Range (TCASE) 55°C to +125°C
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
