| HMC620LC4 v01.1007 GaAs MMIC I/Q MIXER 3 - 7 GHz Typical Applications The HMC620LC4 is ideal for: * Point-to-Point * Point-to-Multi-Point Radio * WiMAX & Fixed Wireless Features Wide IF Bandwidth: DC - 3.5 GHz High Image Rejection: 32 dB High LO to RF Isolation: 43 dB High Input IP3: +22 dBm 24 Lead Ceramic 4x4 SMT Package: 16mm2 8 MIXERS - SMT * VSAT Functional Diagram General Description The HMC620LC4 is a compact I/Q MMIC mixer in a leadless "Pb free" RoHS compliant SMT package, which can be used as either an Image Reject Mixer (IRM) or a Single Sideband Upconverter. The mixer utilizes two standard Hittite double balanced mixer cells and a 90 degree hybrid fabricated in a GaAs MESFET process. A low frequency quadrature hybrid was used to produce a 100 MHz upper side band (USB) IF output. This product is a much smaller and more consistent alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies. The HMC620LC4 is compatible with high volume surface mount manufacturing techniques.

These pins may be connected to RF/DC ground without affecting performance. Interface Schematic N/C GND 8 MIXERS - SMT These pins and package bottom must be connected to RF/DC ground. 4 RF This pin is DC coupled and matched to 50 Ohms. 9 IF1 11 IF2 This pin is DC coupled. For applications not requiring operation to DC, this port should be DC blocked externally using a series capacitor whose value has been chosen to pass the necessary IF frequency range. For operation to DC, this pin must not source/sink more than 3mA of current or part non-function and possible part failure will result. 15 LO This pin is DC coupled and matched to 50 Ohms. 8 - 196 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC620LC4 v01.1007 GaAs MMIC I/Q MIXER 3 - 7 GHz Evaluation PCB 8 MIXERS - SMT List of Materials for Evaluation PCB 109998 [1] Item J1 - J2 J3 - J4 U1 PCB [2] Description PCB Mount SMA RF Connector, SRI PCB Mount SMA Connector, Johnson HMC620LC4 109996 Evaluation Board [1] Reference this number when ordering complete evaluation PCB [2] Circuit Board Material: Rogers 4350 The circuit board used in the final application should use RF circuit design techniques.
