ESD sensitive device. Exceeding any one or a combination of the Absolute Maximum Rating conditions may cause permanent damage to the device. Extended application of Absolute Maximum Rating conditions to the device may reduce device reliability. Specified typical performance or functional operation of the device under Absolute Maximum Rating conditions is not implied. RoHS status based on EUDirective2002/95/EC (at time of this document revision). The information in this publication is believed to be accurate and reliable. However, no responsibility is assumed by RF Micro Devices, Inc. ("RFMD") for its use, nor for any infringement of patents, or other rights of third parties, resulting from its use. No license is granted by implication or otherwise under any patent or patent rights of RFMD. RFMD reserves the right to change component circuitry, recommended application circuitry and specifications at any time without prior notice. NOTE: Exceeding any one or a combination of the above maximum rating limits may cause permanent damage. Input RF transients to +15dBm will not harm the device. For sustained operation at inputs >+5dBm, a small dropping resistor is recommended in series with the VCC in order to limit the current due to self-biasing to <32mA.

Higher supply voltages such as 5V are permissible if a series resistor is used to drop VCC to <4.0V for a given ICC. 2 of 6 7628 Thorndike Road, Greensboro, NC 27409-9421 * For sales or technical support, contact RFMD at (+1) 336-678-5570 or sales-support@rfmd.com. Rev A7 DS071115 RF2370 Pin 1 Function BIAS Description For low noise amplifier applications, this pin is used to control the bias current. An external resistor can be used to set the bias current for any VBIAS voltage. Interface Schematic V B IA S 2 3 GND1 RF IN Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. RF input pin. This part is designed such that 50 is the optimal source impedance for best noise figure. Best noise figure is achieved with only a series capacitor on the input. RF IN To Bias Circuit RF OUT 4 RF OUT 5 GND2 Amplifier output pin. This pin is an open-collector output. It must be biased to VCC through a choke or matching inductor. This pin is matched to 50 with a shunt L, series L topology enhances to stability of the device by reducing the high frequency gain above 6GHz. See GND1. 6 GAIN SELECT This pin selects high gain and bypass modes. Gain Select<0.8V, high gain. Gain Select>1.8V, low gain. A series resistor of 100 is required on this pin to enhance stability.
