The HMC521ACHIPS is a passive, compact, inphase/quadrature (I/Q) monolithic microwave integrated circuit (MMIC) mixer that can be used either as an image reject mixer for receiver operations or as a single sideband upconverter for transmitter operations. With a RF and local oscillator (LO) range of 8.5 GHz to 13.5 GHz, and an intermediate frequency (IFx) bandwidth of dc to 3.5 GHz, the HMC521ACHIPS is ideal for applications requiring excellent RF performance and a simple design with fewer components. A single HMC521ACHIPS can replace multiple narrow-band mixers in a design. The inherent I/Q architecture of the HMC521ACHIPS offers exceptional image rejection and thereby eliminates the need for expensive filtering for unwanted sidebands. The mixer also provides high LO to RF isolation (>35 dB) and reduces the effect of LO leakage to ensure signal integrity. Being a passive mixer, the HMC521ACHIPS does not require any dc power sources. The device offers a lower noise figure compared to an active mixer, ensuring outstanding dynamic range for high performance and precision applications. The HMC521ACHIPS is fabricated on a gallium arsenide (GaAs), metal semiconductor field effect transistor (MESFET) process and uses Analog Devices, Inc., mixer cells and a 90 degree hybrid. The HMC521ACHIPS operates over a −40 C to +85 C temperature range.
