Abstract
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.
