High-performance standard and custom-designed signal sources. Surface-mount and modular Phase-Locked Oscillators (PLO) and Frequency Synthesizers (PLL). Products include Fixed-frequency and serially-programmable VCO, CRO and YIG-based phase-locked product designs. (4 MHz to over 18 GHz).

Modular RF Components - EM Research
The ESP-100 and ESP-200 from EM Research were designed as local oscillators in high level mixers designed to test picocell and femtocell base stations. The ESP-100 and ESP-200 operate fixed at 100 MHz and 200 MHz, respectively, and feature extremely low phase noise, (<-130 dBc/Hz @ 100 KHz, typical).
