MICROWAVE CORPORATION HMC423MS8 v01.0603 GaAs MMIC MIXER w/ INTEGRATED LO AMPLIFIER, 0.6 - 1.3 GHz Typical Applications Features The HMC423MS8 is ideal for: Integrated LO Amplifier w/ Pdiss <50 mW • Base Stations Conversion Loss / Noise Figure: 8.0 dB • Portable Wireless Low LO Drive: 0 dBm • CATV/DBS Input IP3: +15 dBm • ISM Single Positive Supply: 3V, 15 mA Functional Diagram General Description MIXERS - SMT 12 The HMC423MS8 is a double balanced mixer IC with an integrated LO amplifier. This mixer can operate as an upconverter or downconverter between 0.6 GHz and 1.3 GHz. With the integrated LO amplifier, the mixer requires an LO drive level of only 0 dBm, and requires only 15mA from a single positive +3V rail. The mixer has 8 dB of conversion loss, an input P1dB of +8 dBm and an input third order intercept point of +15 dBm at 1.3 GHz. Electrical Specifications, TA = +25° C IF = 100 MHz LO = 0 dBm, Vdd = 3V Parameter Min. Typ. Units Max.

One external RF bypass capacitor (10,000 pF) is required. 5 IF Port 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 18 mA of current or die non-function and possible die failure will result. 8 RF Port This pin is DC coupled and matched to 50 Ohm from 0.6 - 1.3 GHz Interface Schematic MIXERS - SMT 12 Application Circuit 12 - 268 C1 10,000 pF L1 4.7 nH For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com MICROWAVE CORPORATION HMC423MS8 v01.0603 GaAs MMIC MIXER w/ INTEGRATED LO AMPLIFIER, 0.6 - 1.3 GHz Evaluation PCB MIXERS - SMT 12 List of Material Item Description J1 - J3 PC Mount SMA Connector, Johnson J4, J5 DC Pin C1 10k pF Chip Capacitor, 0603 Pkg.
