It consists of a single-ended 75 terminated LNA, followed by a differential gain control stage with 30dB of analog gain control and a double-balanced mixer. The mixer load is available via pins 10 and 11 should an external filter be required. The mixer output is connected to an IF amplifier that can be configured from 10dB to 40dB gain with an external resistor. The amplifier is capable of 6V pk-pk output into a 1k load.

Rev A6 DS061016 RF3334 Pin 12 Function RFAGC Description RF Gain select voltage input. The voltage applied to this pin sets the gain of the RF amplifier. The voltage applied to this pin should be between 0.5V and 4.5V. The RF gain characteristic is such that 0.5V yields a gain of -2dB and 4.5V yields a gain of +30dB as measured from the input of the LNA to the output of the mixer stage. Differential LO Input. This pin and pin 14 (LOB) are the differential LO inputs. This input should be AC-coupled. The differential input impedance across pins 13 and 14 is 75. The LO may be driven single ended but will require a higher drive level. If a single ended LO is applied, pin 14 should be AC-coupled to ground.

Typical thickness is 3inch to 8inch gold over 180inch nickel. PCB Land Pattern Recommendation PCB land patterns are based on IPC-SM-782 standards when possible. The pad pattern shown has been developed and tested for optimized assembly at RFMD; however, it may require some modifications to address company specific assembly processes. The PCB land pattern has been developed to accommodate lead and package tolerances. PCB Metal Land Pattern A = 0.69 x 0.28 (mm) Typ. B = 0.28 x 0.69 (mm) Typ. C = 2.40 (mm) Sq.

The solder mask footprint will match what is shown for the PCB metal land pattern with a 2mil to 3mil 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. A = 0.79 x 0.38 (mm) Typ. B = 0.38 x 0.79 (mm) Typ.

PCB Solder Mask Pattern (Top View) 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. 12 of 12 7628 Thorndike Road, Greensboro, NC 27409-9421 * For sales or technical support, contact RFMD at (+1) 336-678-5570 or sales-support@rfmd.com.
