Phase Shifter Component - RF Feed Network

Product Specifications

Technical details and manufacturing context for Phase Shifter

Definition

A phase shifter is an electronic component within a feed network that modifies the phase angle of an electromagnetic signal without significantly altering its amplitude. In feed networks, it is used to control signal timing, beam steering in antenna arrays, impedance matching, and signal synchronization between different transmission paths. This directory entry covers phase shifters used in computer, electronic, and optical product manufacturing, typically as part of RF and microwave systems. The phase shifter operates by introducing a controlled time delay or phase change to the signal, which can be achieved through various methods: changing the electrical length of the transmission path (mechanical or electrical length variation), using variable reactance components such as varactors or PIN diodes to alter phase velocity, implementing switched-line configurations that select different path lengths, or utilizing ferrite materials whose permeability is controlled by magnetic bias. Typical parameters include a frequency range of 0.5–18 GHz, phase shift range of 0–360 degrees (continuous or stepwise), insertion loss ≤1.5 dB, VSWR ≤1.5, phase error ±5 degrees RMS, impedance 50 ohms, power handling 10–100 W (CW, depending on model), operating temperature -40 to 85 °C, control voltage 0–5 V DC (analog or digital), SMA female connectors, switching time ≤100 ns for digital types, dimensions approximately 25×25×10 mm, and weight ≤50 g without cables. Materials commonly used include aluminum alloy, copper, dielectric substrates (PTFE, ceramic), and semiconductor components (PIN diodes, varactors). These values are directory reference ranges and must be confirmed for the specific model and application. Always verify model-specific specifications and applicable standards with the legal manufacturer or supplier before procurement or use.

Working Principle

Phase shifters operate by introducing a controlled time delay or phase change to an electromagnetic signal. This can be achieved through various methods: 1) changing the electrical length of the transmission path (mechanical or electrical length variation), 2) using variable reactance components (varactors, PIN diodes) to alter the phase velocity, 3) implementing switched-line configurations that select different path lengths, or 4) utilizing ferrite materials whose permeability can be controlled by magnetic bias to change phase characteristics. The choice of method depends on the required bandwidth, phase accuracy, switching speed, and power handling.

Frequently Asked Questions

What is the typical frequency range of a phase shifter?

The directory lists a frequency range of 0.5–18 GHz. However, this is a reference range; the actual operating bandwidth depends on the specific model and must be confirmed with the manufacturer.

How is the phase shift controlled?

Phase shift can be controlled either analogically via a DC voltage (0–5 V) or digitally with switching circuits. The control method affects the phase resolution and switching speed. Refer to the datasheet for the exact control interface.

What is the insertion loss and VSWR?

The directory lists maximum insertion loss of 1.5 dB and VSWR of 1.5 over the band. These are typical maximum values; actual performance may vary with frequency and model, so verify with the supplier.

Can a phase shifter handle high power?

The power handling is listed as 10–100 W CW, depending on the model. For high-power applications, ensure the selected phase shifter meets the required power level and thermal conditions.
