The LT series of frequency synthesizers operates with minimal phase noise degradation at random vibration levels exceeding 14 g’s RMS, 20 Hz to 2 kHz. Shielded aluminum housings are surface-mountable, and can be optionally hermetically sealed for use in stringent environments. The products are offered with optional RoHS compliance, lead (Pb)-free and tin-mitigated designs. Ideally suited for use as local oscillators in UAV, re-entry vehicle (sounding rockets) and military ballistics applications. The LT series exhibits negligible microphonics under shock.

Low Profile Bandpass Filter

This low profile bandpass filter is ideal for applications where cable connections are necessary, while maintaining a “z” dimension that is comparable to many surface-mount applications. Measuring at 1 in2, with a “z” height of 0.25", the filter features high performance flexible RF cable assemblies available with “SMP,” as well as other similar types of RF connectors. This allows fast integration, without the necessity of solder reflow that is typical of most surface-mount configurations. The filters are available in center frequencies ranging from 1000 to 6000 MHz, with 3 dB bandwidths, which can be specified at greater than 100 percent of center frequency.

Harmonic Phase Reference

The NM200 is a 20 GHz harmonic phase reference comb generator that produces a precisely characterized repetitive output pulse when a sine wave between 600 MHz and 1.2 GHz is applied. This repetitive pulse consists of a fundamental tone and multiple harmonics up to 20 GHz and the phase relationship between these tones is stable and well known with a given uncertainty up to 20 GHz. It can be used as a unique calibration element to eliminate the phase distortion of any setup, such as a large-signal network analyzer, which is used to characterize active components in a nonlinear mode of operation.
