General Description
 Mimix Broadband’s 32.0-42.0 GHz GaAs MMIC sub-harmonic image reject mixer can be used as an upor down-converter.
The device has a conversion loss of 9.0 dB with 18.0 dB image rejection across the band.
I and Q mixer outputs are provided and an external 90 degree hybrid is required to select the desired sideband.
This MMIC uses Mimix Broadband’s 2 μm GaAs HBT device model technology, and is based upon electron beam lithography to ensure high repeatability and uniformity.
The chip has surface passivation to protect and provide a rugged part with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.

High LO/RF Isolation: 48 dB
Wide IF Bandwidth: DC - 3 GHz
Passive Double Balanced Topology
Low Conversion Loss: 7 dB
Small Size: 1.02 x 0.94 x 0.1 mm

General Description
The HMC557 is a passive double balanced mixer that can be used as an upconverter or downconverter between 2.5 and 7 GHz. The miniature monolithic mixer is fabricated in a GaAs MESFET process, and requires no external components or matching circuitry.
The HMC557 operates with LO drive levels as low as +9 dBm and provides excellent LO to RF and LO to IF isolation due to optimized balun structures.
Measurements were made with the chip mounted into in a 50 ohm test fi xture and includes the parasitic effects of wire bond assembly. Connections were made with a 1 mil wire bond with minimal length (<12 mil).

Output IP3: +37 dBm
Supply Voltage: +12V @ 300 mA
50 Ohm Matched Input/Output
Die Size: 3.38 x 2.05 x 0.1 mm

General Description
The HMC619 is a GaAs MMIC PHEMT Distributed Power Amplifi er die which operates between DC and 10 GHz. The amplifi er provides 12 dB of gain, +37 dBm output IP3 and +28 dBm of output power at 1 dB gain compression while requiring 300 mA from a +12V supply.

Typical Applications
High Dynamic Range Infrastructure:
• Cable Modem Termination Systems

+35 dBm Input IP3
Conversion Loss: 8.8 dB
No External Components
Ultra Small MSOP Package: 14.8mm2

General Description
The HMC400MS8 is a high dynamic range passive MMIC mixer in a plastic surface mount 8 lead Mini Small Outline Package (MSOP) covering 1.7 to 2.2 GHz. Excellent input IP3 performance of +36 dBm for down conversion and +29 dBm for up conversion is provided for 2.5G & 3G GSM/CDMA based UMTS or PCS applications at an LO drive of +17dBm. With a 1dB compression of +21 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 8.5dB typical and LO isolations are maintained at 22 to 33 dB. This miniature singleended monolithic GaAs FET mixer does not require any external components or bias. The 50 to 300 MHz IF frequency response will satisfy many UMTS/PCS transmit or receive frequency plans confi gured for low side LO. The HMC400MS8 input IP3 performance coupled with its high P1dB rivals traditional active FET mixers while offering a much smaller 14.8mm2 standard IC footprint and no DC bias.
