Description

Alpha has redesigned its product line of sampling phase

detectors using automated chip on board manufacturing

technology to provide a more uniform, surface mountable,

small footprint device without sacrificing the microwave

performance of the original design.

Sampling phase detectors are used to phase lock a

microwave VCO to a stable reference source at a

submultiple frequency. The sampling phase detector

consists of a step recovery diode, capacitors and a

microwave mixer consisting of series pair Schottky

diodes. The principle of operation may be described as

using the step recovery diode to generate a harmonic comb

of the reference oscillator frequency and the Schottky diode

as a mixer between the closest reference frequency multiple

and the microwave signal generated by the VCO. When

these frequencies are identical the IF (beat note) signal is

a DC voltage; the IF will be sinusoidal when the

frequencies are unequal.

Schottky diodes used are low capacitance devices

capable of efficient mixer performance at frequencies above

22 GHz. The SPD1101-111, SPD1102-111 and

SPD1103-111 utilize low, medium and high barrier

Schottky diodes and may be selected according to the

available power generated by the microwave VCO.

The SPD1100 series sampling phase detectors use a

selected step recovery diode chip whose carrier lifetime and

transition time are appropriate for use in applications

allowing reference frequencies below 50 MHz and

microwave VCO frequencies as high as 22 GHz. The
