Frequency Sources

Frequency Sources 18GHz up to 110GHz

Spacek Labs offers three categories of frequency sources from 18GHz up to 110GHz.

 

Gunn Oscillators– These are relatively inexpensive stable sources, that can be fixed, mechanical or varactor tuned.

Frequency Synthesizers – A lower frequency synthesizer is multiplied, amplified and filtered to produce a clean and stable band of frequencies in the millimeter-wave frequency range.

Phase-Locked Sources – Single Frequency Phase Locked Oscillators in Ku band are multiplied, amplified and filtered to produce a clean and stable output in the millimeter-wave frequency range.

These transceivers are designed to offer premium performance at a fair price, offer separate two-channel, full-duplex designs and use a common phase-locked local oscillator driving two mixers. The upconverting mixer has a bandpass filter followed by an optional power amplifier on the output. The downconverting mixer can have an optional low-noise amplifier in front of it. Output powers of up to 1 watt and noise figures as low as 4.0 dB are available. Cross channel isolation is greater than 60 dB. Also available are multiple channel versions – i.e. one upconverter channel and two to four downconverter channels. Any LO frequency can be chosen to optimize the IF band.

Frequency Conversion

Mixers – A RF/mmWave mixer translates the input signal frequency to an output signal of a different frequency. The translation can be either from a lower frequency to a higher frequency or vice versa.

 

he important factors that we look for in mixers are its conversion loss, multi-tone intermodulation, single tone spurious and isolations. These are all parameters that could affect the dynamic range of a RF/mmWave system. Our mixers cover the frequency range from 10 to 110 GHz and have excellent conversion loss/gain.

Up / Down Converters – up or down converters are built to customer’s needs. It offers great flexibility including the choices of internal local oscillator (LO) as well as internal amplifier (including PA or LNA). It is custom made to provide our customers the most suitable up / down converters for their applications. Some of these applications include Point-to-Point radio, broadband communications, and RADAR applications. It is also excellent in performance as we optimized all the internal circuitry including image rejection, LO or RF buffer, LO multiplications, filtering as well as all the bias networks. Also available Dual band up or down converters for customers who are looking for both 28 GHz and 39 GHz converters and offered in connectorized box for easy installing. Models with built-in LNA or PA are also available.
