Waveguide Broadwall Coupler
RLC Electronics offers a standard range of multi-hole broadwall directional couplers covering the frequencies from 40 to 2.6 GHz in standard waveguide sizes. The electrical characteristics of high directivity and coupling flatness are achieved by using a precise machined coupling hole pattern and a precision load in the secondary arm. Non-standard configurations or selected electrical parameters are available on request.
SMD-packaged SAW-oscillators are extensively used in modern communication applications, since the technology features low phase noise, low microphonic (tolerance to vibration) and low jitter. SAW-oscillators exhibit limited tuning and limited operating temperature range (-20°C to 70°C), which limits the amount of correction needed to compensate frequency-drifts and tolerances of other components in the oscillator circuitry. The alternative is ovenized SAW-oscillators for extending the operating temperature but at the cost of high current and increase in size.
