The Fundamentals Of Phase-Locked Oscillators By AtlanTecRF
The phase-locked oscillator (PLO) is a versatile low-noise signal source that is available in different architectures to suit different applications and environments. The purpose of this article is to review the fundamentals of PLOs and describe some of the most popular types.
Spotlight On Oscillators
10- To 50-MHz TCXO — 3 x 5 mm Greenray Industries' T52 TCXO has been developed as a reference oscillator for timing applications requiring low noise, low power draw, tight stability over temperature, and a compact footprint. It is ideal for small cell and femtocell applications, for example.
Radiation-Tolerant, Voltage-Controlled SAW Oscillator The AP725 Series of high-performance SAW oscillators from API Technologies provides superior performance at operating frequencies of 350 MHz to 4,000 MHz. In addition, by employing a domestic, in-house SAW wafer fab, API’s design engineers are able to provide superior quality control resulting in consistently designed high-quality products.
Oscillator For Telecommunications The PE5 is a hermetically sealed oscillator with 0.3 ps jitter over the telecommunication industry standard carrier offset of 12 kHz to 20 MHz. It’s specifically designed for telecom clocking applications.
5-MHz To 26-GHz Phase Noise Tester With 50-MHz Offset This phase noise tester covers the 5-MHz to 26-GHz frequency range and features a 50-MHz offset. It’s suitable for general-purpose phase noise tests, automated production testing, crystal oscillator and VCO testing, supply noise verification, and PLL synthesizer locking and characterization.
Rugged HCMOS Crystal Clock Oscillator This oscillator comes in a hermetically sealed 5 x 7 mm package that has been designed to withstand harsh and rugged environmental conditions. It covers the 20-kHz to 100-MHz frequency range and features excellent stability, low phase noise, and ultra-low jitter.
Miniature TCXOs For Secure Communications Today we depend on instant communication — data, voice, video — anywhere, anytime, but how can we be sure the digital wireless ‘line’ we’re using goes straight to the right destination? In use today in switches and routers, found inside portable communications devices, and serving as the master clock for encryption/decryption systems, MtronPTI’s high-stability TCXOs have long been trusted to keep the data moving.

This datasheet contains specifications for Phonon’s 101654.100 1200-MHz VCSO (voltage-controlled SAW oscillator). This oscillator is suited for analog signal processing in radar, communications, electronic warfare (EW), and other defense and space applications.
Pascall OCXOs are designed to meet the increasing demand for high-performance reference oscillators. Oven-controlled SC-cut crystals are used to give good temperature stability combined with the lowest possible phase noise.
TRM builds three- and four-port directional couplers and dual directional couplers using lumped element, airline, or stripline technology. This guide details basic coupler parameters and various types including broadband, dual directional, and multi-octave.
Teledyne Microwave Solutions offers several different models of voltage-controlled oscillators with varying frequency ranges, tuning voltage ranges, power outputs, modulation sensitivity, phase noise, harmonic suppression, and DC bias.
