As Teledyne e2v HiRel continues to expand its RF product line, a new radiation tolerant, double-balanced Mixer at 18-46 GHz has been released. For K- and Ka-band communications links, it offers the space design community a Mixer with low conversion loss, high linearity, and a wide IF bandwidth. It is ideally suited for use in designing an up or down-conversion stage in signal chains for radar, satellite transponders, and related RF comms circuits in electronic warfare application.
The first, model TDLM025100, is a 2.5 GHz, 100 W RF power limiter. The second limiter, model TDLM06100, is a 6.0 GHz, 100 W solution. Both are radiation tolerant, monolithic ‘all-in-one’ limiters based on Silicon-on-Insulator technology that are ideal for high reliability aerospace and defense applications. Both offer alternatives to the traditional industry alternative of discrete GaAs PIN diode circuits with multiple external components.
