The Honeywell HMC2003 is a high sensitivity, threeaxis magnetic sensor hybrid assembly used to measure low magnetic field strengths. Honeywell's most sensitive magneto-resistive sensors (HMC1001 and HMC1002) are utilized to provide the reliability and precision of this magnetometer design. The HMC2003 interface is all analog with critical nodes brought out to the pin interfaces for maximum user flexibility. The internal excitation current source and selected gain and offset resistors, reduces temperature errors plus gain and offset drift. Three precision low-noise instrumentation amplifiers with 1kHz low pass filters provide accurate measurements while rejecting unwanted noise.

HMC203 General Description
The HMC203 chip is a miniature double-balanced mixer which can be used as an upconverter or downconverter. Excellent isolations are provided by on-chip baluns, which require no external components and no DC bias. The mixer chip can be integrated directly into MMIC hybrid applications. Unless otherwise stated, all data was measured with the mixer mounted in a MMIC test fi xture. The MMIC was connected to thinfi lm 50 ohm transmission lines with 1 mil diameter wirebonds of <10 mils in length.

HMC204 General Description
The HMC204 is a passive miniature frequency doubler in a MMIC die. Suppression of undesired fundamental and higher order harmonics is 38 dB typical with respect to input signal level. The doubler utilizes the same GaAs Schottky diode/balun technology found in Hittite MMIC mixers. It features small size, no DC bias, and no measurable additive phase noise onto the multiplied signal.
