| HMC524LC3B v01.1106 GaAs MMIC I/Q MIXER 22 - 32 GHz Typical Applications The HMC524LC3B is ideal for: * Point-to-Point Radios Features Wide IF Bandwidth: DC - 4.5 GHz Image Rejection: 20 dB LO to RF Isolation: 45 dB High Input IP3: +20 dBm RoHS Compliant 3x3 mm SMT Package 8 MIXERS - I/Q MIXERS / IRM - SMT * Point-to-Multi-Point Radios & VSAT * Test Equipment & Sensors * Military End Use Functional Diagram General Description The HMC524LC3B is a compact I/Q MMIC mixer which can be used as either an Image Reject Mixer or a Single Sideband Upconverter. The chip utilizes standard Hittite 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 USB IF output. This product is a much smaller alternative to hybrid style Image Reject mixers and single sideband upconverter assemblies. The HMC524LC3B eliminates the need for wirebonding, allowing the use of surface mount techniques.

Interface Schematic GND 8 MIXERS - I/Q MIXERS / IRM - SMT 2 RF This pad is AC coupled and matched to 50 Ohms. 4 IF1 6 IF2 This pad 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 pad must not source/sink more than 3mA of current or die nonfunction and possible die failure will result. No connection required. These pins may be connected to RF/DC ground without affecting performance 5 N/C 9 LO This pad is DC coupled and matched to 50 Ohms. 8 - 122 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 HMC524LC3B v01.1106 GaAs MMIC I/Q MIXER 22 - 32 GHz Evaluation PCB 8 MIXERS - I/Q MIXERS / IRM - SMT List of Materials for Evaluation PCB 109998 [1] Item J1 - J2 J3 - J4 U1 PCB [2] Description PCB Mount K RF Connector, SRI PCB Mount SMA Connector, Johnson HMC524LC3B Mixer 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. Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown.
