Rev A8 DS060918 RF2192 Pin 1 2 3 4 Function GND GND GND RF IN Description Ground connection. Ground connection. Ground connection. RF input. An external 100pF series capacitor is required as a DC block. In addition, shunt inductor and series capacitor are required to provide 2:1VSWR. RF IN From Bias GND1 Stages VCC1 100 pF Interface Schematic 5 6 7 8 9 10 VREG1 VMODE VREG2 BIAS GND GND RF OUT Power Down control for first stage. Regulated voltage supply for amplifier bias. In Power Down mode, both VREG and VMODE need to be LOW (<0.5V). For nominal operation (High Power Mode), VMODE is set LOW. When set HIGH, the driver and final stage are dynamically scaled to reduce the device size and as a result to reduce the idle current. Power Down control for the second stage. Regulated voltage supply for amplifier bias. In Power Down mode, both VREG and VMODE need to be LOW (<0.5V). Bias circuitry ground. See application schematic. Ground connection. RF output and power supply for final stage. This is the unmatched collector output of the second stage. A DC block is required following the matching components. The biasing may be provided via a parallel L-C set for resonance at the operating frequency of 824MHz to 849MHz. It is important to select an inductor with very low DC resistance with a 1A current rating. Alternatively, shunt microstrip techniques are also applicable and provide very low DC resistance. Low frequency bypassing is required for stability. Same as pin 10. Same as pin 10. Harmonic trap. This pin connects to the RF output but is used for providing a low impedance to the second harmonic of the operating frequency. An inductor or transmission line resonating with an on chip capacitor at 2fo is required at this pin. Power supply for bias circuitry. A 100pF high frequency bypass capacitor is recommended. Power supply for first stage. Same as Pin 15. Ground connection. The backside of the package should be soldered to a top side ground pad which is connected to the ground plane with multiple vias. The pad should have a short thermal path to the ground plane.

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 = 0.51 x 0.89 (mm) Typ. B = 0.89 x 0.51 (mm) Typ. C = 1.52 (mm) Sq. 3.20 Typ. 0.81 Typ.

Rev A8 DS060918 RF2192 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 3mil expansion to accommodate solder mask registration clearance around all pads. The centergrounding 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 = 0.71 x 1.09 (mm) Typ. B = 1.09 x 0.71 (mm) Typ.

PCB Solder Mask (Top View) Thermal Pad and Via Design The PCB metal land pattern has been designed with a thermal pad that matches the exposed 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.
