| HMC144LC4 v00.0904 GaAs MMIC DOUBLE-BALANCED MIXER, 6 - 20 GHz Typical Applications The HMC144LC4 is ideal for: * Point-to-Point Radios Features +23 dBm Input IP3 35 dB LO/RF Isolation IF Bandwidth : DC to 3 GHz RoHS Compliant 4x4 mm SMT Package 7 MIXERS - SMT * Point-to-Mulit-Point Radios & VSAT * Test Equipment & Sensors * Military End-Use Functional Diagram General Description The HMC144LC4 is a Double-Balanced MMIC Mixer in a leadless "Pb free" SMT package which can be used as an upconverter or downconverter from 6 to 20 GHz. Broadband operation and 30 to 40 dB isolations are provided by on-chip baluns, which require no external components or DC bias. MMIC mixers are more reliable replacements to hybrid diode mixers assuring consistent conversion loss and isolation performance over high volume production lots. The HMC144LC4 eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques. Electrical Specifications, TA = +25 C Parameter Min.

These pins may be connected to RF/DC ground. Performance will not be affected. These pins and package bottom must be connect to RF/DC ground. Interface Schematic 7 MIXERS - SMT 2, 4, 8, 10, 15, 17 GND 3 RF This pin is AC coupled and matched to 50 Ohms from 6 - 20 GHz 9 IF 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 2 mA of current or die non-function and possible die failure will result. 16 LO This pin is AC coupled and matched to 50 Ohms from 6 - 20 GHz 7 - 34 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 HMC144LC4 v00.0904 GaAs MMIC DOUBLE-BALANCED MIXER, 6 - 20 GHz Evaluation PCB 7 MIXERS - SMT List of Materials for Evaluation PCB 109010 Item J1 - J2 J3 U1 PCB [2] Description PCB Mount SMA RF Connector, SRI PCB Mount SMA Connector, Johnson HMC144LC4 109005 Evaluation Board [1] [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.
