Wideband downconversion mixers are demonstrated by using both 0.35‐μm SiGe heterojunction bipolar transistor (HBT) and 2‐μm GaInP/GaAs HBT technologies. A micromixer topology is implemented in the RF port while a differential type shunt–shunt feedback amplifier and a differential‐to‐single CE‐CC output buffer are used in the IF stage. The frequency response analysis and systematic measurement approach for a wideband Gilbert mixer are proposed in this article for each individual stage of local frequency (LO), radio frequency (RF), and intermediate frequency (IF). The differential LO signals are generated by several off‐chip 180° hybrids to cover more than 8:1 bandwidth. The SiGe HBT Micromixer achieves the conversion gain of 6 dB, IP1dB of −17.5 dBm, and IIP3 of −7 dBm with the 3.3‐V supply voltage and the power consumption of 37.5 mW. On the other hand, the GaInP/GaAs HBT Micromixer achieves the conversion gain of 25 dB, IP1dB of −25 dBm, and IIP3 of −15 dBm with the 5‐V supply voltage and the power consumption of 50 mW. © 2008 Wiley Periodicals, Inc.

WASP2 is a lag correlation spectrometer that is optimized for astronomical heterodyne observations of spectral lines from mid-infrared through centimeter wavelengths. Since the instrument is a wideband microwave spectrum analyzer, its basic technology is well suited to radio astronomy, atmospheric remote sensing, and any other application which requires observations of broad spectral lines. In this specific instrument, eight 16 lag correlator boards form a 128 lag spectrometer with 33 MHz spectral resolution. The spectrometer's present microwave components dominate its gain shape, yielding a spectrometer which covers a useful ͑6 dB bandwidth͒ single band of 3600 MHz, from 280 to 3880 MHz. The correlator boards have a 3 dB bandwidth of 4000 MHz, from below 100 MHz to near their aliasing limit of 4200 MHz. WASP2 obtains its wide bandwidth with fully analog high frequency components: the voltage multipliers are transistor circuits and the delays are lengths of microstrip transmission line. WASP2 is simple, compact, requires little power, and integrates stably for many hours.
