摘要： A spectrum analyzer that provides from below 9 kHz to above 20 GHz operation range while remaining hand-held. The spectrum analyzer includes an integrated precision stand-alone step attenuator that does not rely on printed circuit board (PCB) mounted circuit elements within the signal path. Further, a PIN diplexing switch separates signals into different base-band and highband paths. The baseband path includes a pre-amplifier for low frequency signals, while the higher frequency bands may not necessarily include a pre-amplifier. The highband path incorporates multi-throw MMIC PIN diode switches to selectively filter different bands of input signals.

摘要： A spectrum analyzer is provided that includes components to achieve from below 9 kHz to above 20 GHz operation range while remaining hand-held. Components of the spectrum analyzer include an integrated precision stand-alone step attenuator that does not rely on printed circuit board (PCB) mounted circuit elements within the signal path. Further, a PIN diplexing switch separates signals into different base-band and highband paths. The baseband path includes a pre-amplifier for low frequency signals, while the higher frequency bands may not necessarily include a pre-amplifier. The baseband path further provides improved broadband termination of its 1st mixer IF port by incorporating a new quadrature-coupled directional (QCD) filter that includes a ring resonator. An inexpensive air dielectric multi-cavity baseband filter is also used to suppress 2nd mixer IF images. The highband path incorporates multi-throw MMIC PIN diode switches to selectively filter different bands of input signals. At least three total 1st mixers are used to increase operation bandwidth. A phase locked loop providing a 1st LO to the 1st mixers is created that uses a divide-by-two frequency divider in cascade with a sampler-type frequency downconverter. The output of the 1st LO is frequency doubled and filtered to increase the frequency range of the highband signal path.
