The HMC650/HMC651/HMC652/HMC653/HMC654/HMC655/HMC656/HMC657/HMC658are a line of wideband fixed value 50 Ohm matched attenuator chips which offer relative attenuation levels of 0, 2, 3, 4, 6, 10, 15 and 20 dB. These passive thoughlines and attenuators are ideal for microstrip, hybrid, and multi-chip module applications where extremely flat attenuation, and excellent VSWR vs. frequency are required.These wideband attenuators feature low inductance on-chip vias, and require no additional ground connections. The HMC650 through HMC658 are backside metallized with gold, and are suitable for eutectic or epoxy die attach. Each of the 9 products can be purchased individually by their respective part number or in a set of 10 each in the HMC-DK006 Fixed Attenuator Chip Designer’s Kit.ApplicationsFiber OpticsMicrowave RadioMilitary & Space HybridsTest & MeasurementScientific InstrumentsRF/Microwave Circuit Prototyping

The HMC6505A is a compact gallium arsenide (GaAs), pseudomorphic (pHEMT), monolithic microwave integrated circuit (MMIC) upconverter in a RoHS compliant package that operates from 5.5 GHz to 8.6 GHz. This device provides a small signal conversion gain of 15 dB with 22 dBc of sideband rejection. The HMC6505A uses a variable gain amplifier (VGA) preceded by an in-phase and quadrature (I/Q) mixer that is driven by an active local oscillator (LO). The IF1 and IF2 mixer inputs are provided, and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering of unwanted sideband. The HMC6505A is a smaller alternative to hybrid style single sideband (SSB) upconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface-mount manufacturing techniques.The HMC6505A is available in 5 mm × 5 mm, 32-terminal leadless chip carrier (LCC) package and operates over a −40°C to +85°C temperature range. An evaluation board for the HMC6505A is also available upon request.ApplicationsPoint to point and point to multipoint radiosMilitary radars, electronic warfare (EW), and electronic intelligence (ELINT)Satellite communicationsSensors
