| RF2361 4 Typical Applications * TDMA/CDMA/FM Cellular PCS LNA * Low Noise Transmit Driver Amplifier * General Purpose Amplification * Commercial and Consumer Systems 3V LOW NOISE AMPLIFIER/ 3V PA DRIVER AMPLIFIER Product Description The RF2361 is a low noise amplifier with a very high dynamic range designed for digital cellular applications. The device functions as an outstanding front end low noise amplifier or power amplifier driver amplifier in the transmit chain of digital subscriber units where low transmit noise power is a concern. When used as an LNA, the bias current can be set externally. When used as a PA driver, the IC can operate directly from a single cell Li-ion battery and includes a power down feature that can be used to completely turn off the device. The IC is featured in a standard SOT 5-lead plastic package. 1.60 + 0.01 0.400 1 4 GENERAL PURPOSE AMPLIFIERS 0.15 0.05 2.90 + 0.10 0.950 2.80 + 0.20 3 MAX 0 MIN 0.45 + 0.10 0.127 1.44 1.04 Dimensions in mm.

This pin is DC coupled and matched to 50 at 836 MHz. Interface Schematic To Bias Circuit RF OUT RF IN 2 3 GND1 VPD Ground connection. Keep traces physically short and connect immediately to ground plane for best performance. For low noise amplifier applications, this pin is used to control the bias current. See plots for bias current settings. An external resistor (R1) can be used to set the bias current for any VPD voltage. For driver amplifier applications, this is the Power Down pin for the IC. VPD =2.8V +/- 0.1V is required for proper operation. VPD< 0.9V turns off the Part. External RF bypassing is required. The trace length between the pin and the bypass capacitors should be minimized. The ground side of the bypass capacitors should connect immediately to ground plane. Nominal current required for VPD =2.8V is 2.0mA typical and 3.0mA Max (@ VPD =2.9V). PD 4 GENERAL PURPOSE AMPLIFIERS 4 RF OUT 5 GND2 Amplifier Output pin. This pin is an open-collector output. It must be biased to either VCC or pin 4 through a choke or matching inductor. This pin is typically matched to 50 with a shunt bias/matching inductor and series blocking/matching capacitor. Refer to application schematics. Ground connection. Keep traces physically short and connect immediately to ground plane for best performance. 4-186 Rev A7 001201 RF2361 Application Schematic: Low Noise Amplifier ~881MHz Operation J1 RF IN 22 nF 1 5 2 1k VPD 10 nF 100 pF 3 4 12 nH VCC 100 pF 10 nF 2 pF J2 RF OUT 4 GENERAL PURPOSE AMPLIFIERS Application Schematic: Low Noise Amplifier ~1950MHz Operation J1 RF IN 22 nF 1 5 2 1k VPD 10 nF 100 pF 3 4 3.3 nH VCC 100 pF 10 nF 1 pF J2 RF OUT Rev A7 001201 4-187 RF2361 Application Schematic: Driver Amplifier ~836MHz Operation J1 RF IN 22 nF 1 5 2 0 VPD 3 10 nF 100 pF 4 12 nH VCC 100 pF 10 nF 2 pF J2 RF OUT 4 GENERAL PURPOSE AMPLIFIERS Application Schematic: Driver Amplifier ~1880MHz Operation J1 RF IN 22 nF 1 5 2 0 VPD 10 nF 100 pF 3 4 3.3 nH VCC 100 pF 10 nF 1 pF J2 RF OUT 4-188 Rev A7 001201 RF2361 Evaluation Board Schematic: Low Noise Amplifier ~881MHz Operation (Download Bill of Materials from www.rfmd.com.)
