The excellent linearity performance achieved by the RF1604 make it ideal for use in multimode GSM/EDGE/WCDMA, LTE, and cellular infrastructure applications. The RF1604 offers very high isolation between the RF ports, providing greater RF separation between the transmit and receive paths, which is critical in full-duplex systems. Additionally, RF1604 includes integrated decoding logic, allowing just two control lines needed for switch control. The RF1604 is packaged in a very compact 2.5mmx2.5mm, 12pin, leadless QFN package.

When VDD is high, the switch is active. The start-up time is defined as the delay time that control signal(s) cross 0.8V threshold until KF output level is 90% of final RF voltage peak. Power Sequence ON Sequence: First turn ON VDD, then apply control signals. OFF Sequence: First turn OFF the control signals, then turn OFF VDD. Note: Not following the power ON/OFF sequence could cause damage to the switch and may affect the long-term reliability of the device. Electrical Test Methods The electrical parameters for the switch were measured on RFMD evaluation board. The test PWB includes means for decoupling RF signals from control signal port (shunt capacitor at control signal ports). All measurements are done with calibration plane at switch pins. The effect of test board losses and phase delay has been removed from the results.

DS120125 RF1604 PCB Design Requirements PCB Surface Finish The PCB surface finish used for RFMD's qualification process is electroless nickel, immersion gold. Typical thickness is 3inch to 8inch gold over 180inch nickel. PCB Land Pattern Recommendation PCB land patterns for RFMD components are based on IPC-7351 standards and RFMD empirical data. The pad pattern shown has been developed and tested for optimized assembly at RFMD. The PCB land pattern has been developed to accommodate lead and package tolerances. Since surface mount processes vary from company to company, careful process development is recommended. PCB Metal Land Pattern DS120125 7628 Thorndike Road, Greensboro, NC 27409-9421 · For sales or technical support, contact RFMD at (+1) 336-678-5570 or [email protected]. 7 of 9 RF1604 PCB Solder Mask Pattern Liquid Photo-Imageable (LPI) solder mask is recommended. The solder mask footprint will match what is shown for the PCB metal land pattern with a 2 mil to 3 mil expansion to accommodate solder mask registration clearance around all pads. The center-grounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask clearance can be provided in the master data or requested from the PCB fabrication supplier. Thermal Pad and Via Design The PCB land pattern has been designed with a thermal pad that matches the die paddle size on the bottom of the device. Thermal vias are required in the PCB layout to effectively conduct heat away from the package. The via pattern has been designed to address thermal, power dissipation and electrical requirements of the device as well as accommodating routing strategies. The via pattern used for the RFMD qualification is based on thru-hole vias with 0.203mm to 0.330mm finished hole size on a 0.5mm to 1.2mm grid pattern with 0.025mm plating on via walls. If micro vias are used in a design, it is suggested that the quantity of vias be increased by a 4:1 ratio to achieve similar results. 8 of 9 7628 Thorndike Road, Greensboro, NC 27409-9421 · For sales or technical support, contact RFMD at (+1) 336-678-5570 or [email protected].
