| ML401 Product Features * High dynamic range mixer with integrated LO driver * +31 dBm Input IP3 * 8 dB Conversion Loss * RF: 1700 - 2200 MHz * LO: 1550 - 2150 MHz * IF: 50 - 250 MHz * 0 dBm Drive Level * RoHS-compliant SOIC-8 pkg The Communications Edge TM Product Information 1.7-2.2 GHz High IP3 Mixer with Integrated LO Amp Product Description The ML401 high linearity upconverter or downconverter combines a passive GaAs MESFET mixer with an integrated HBT LO driver in a low-cost leadfree/green/RoHS-compliant SOIC-8 package. WJ's ML401 uses patented techniques to realize +31 dBm Input IP3 with 8 dB conversion loss using an LO drive level of 0 dBm in a downconverting application. The on-chip diplexer in the mixers allows for good matching on the RF and IF ports. The dual-stage LO driver provides a stable input power level into the mixer to allow for consistent performance over a wide range of LO power levels. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in 2.5G and 3G GSM/CDMA/W-CDMA systems in the DCS, PCS, or UMTS frequency bands.

IIP3 is measured with f = 1 MHz with RFin = 0 dBm / tone. LO is injected with 0 dBm. This refers to the operating current under LO drive. The current can be reduced by increasing the value of the R2 resistor slightly.

Vias should use a .35mm (#80 / .0135") diameter drill and have a final plated thru diameter of .25 mm (.010"). 2. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance. 3. Mounting screws can be added near the part to fasten the board to a heatsink. Ensure that the ground / thermal via region contacts the heatsink. 4. All dimensions are in millimeters (inches). Angles are in degrees. 5. Do not put solder mask on the backside of the PC board in the region where the board contacts the heatsink. 6. RF trace width depends upon the PC board material and construction. 7. Use 1 oz.
