3 / 10 page 3 of 10 RF5152 DS110617 7628 Thorndike Road, Greensboro, NC 27409-9421 · For sales or technical support, contact RFMD at (+1) 336-678-5570 or sales-support@rfmd.com. Pin Function Description Interface Schematic 1NC Not connected. May be connected to ground (GND). 2RF IN RF input. See evaluation board schematic for details. 3RF IN RF input. See evaluation board schematic for details. 4NC Not connected. Note: Connection of VC1 at this pin will not damage the RF5152 or adversely affect RF5152 performance. 5VCC Supply voltage for the bias reference and control circuits. May be con- nected with VC1, VC2 and VC3 with a single-supply voltage as long as VCC does not exceed 3.3VDC in this configuration. 6VB1/VB2 Bias current control voltage for the first and second stages. 7VB3 Bias current control voltage for the third stage. 8NC Not connected. 9PDETECT Provides an output voltage proportional to the output RF level. 10 RF OUT RF output. The output requires external matching components which con- sist of a one or two shunt capacitors and a series capacitor for DC blocking. 11 RF OUT Same as pin 10. See pin 10. 12 RF OUT/ VC3 RF output and bias for the output stage. The power supply for the output transistor needs to be supplied to this pin. This can be done through a quarter-wave ( o/4) length microstrip line that is RF grounded at the other end, or through an RF inductor that supports the required DC current. See evaluation board schematic. See pin 10. 13 NC Not connected. May be connected to ground (GND). 14 VC2 Second stage power supply input. Connect as shown on evaluation board schematic. 15 NC Not connected. May be connected to ground (GND). 16 VC1 First stage power supply input. Connect as shown on evaluation board schematic. Pkg Base GND Ground connection. The back side of the package should be connected to the ground plane through as short a connection as possible (e.g., PCB vias under the device are required).
