RF2369

RF2369 0 RoHS Compliant & Pb-Free Product Typical Applications • CDMA/Cellular Bypass LNA • CDMA/Cellular Bypass Driver Amplifier • General Purpose Amplification • Commercial and Consumer Systems 3V LOW NOISE AMPLIFIER/ 3V PA DRIVER AMPLIFIER Product Description The RF2369 is a switchable 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. 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 6-lead plastic package. 1.80 1.40 0.50 0.35 0.10 MAX. TEXT* 1.90 3.10 2.70 3.00 2.60 Shaded lead is pin 1.

An external resistor can be used to set the bias current for any VPD voltage. Interface Schematic VREF/PD 2 3 GND1 RF IN Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. RF input pin. To Bias Circuit RF OUT RF IN 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 typically matched to 50 Ω with a shunt bias/matching inductor and series blocking/matching capacitor. Refer to application schematics. LNA emittance inductance. Total inductance is comprised of package+bondwire+stripline (L1) on PCB. 6 SELECT This pin selects high gain and bypass. Select < 0.8V, high gain. Select > 1.8V, low gain. 4-404 Rev B2 061016 RF2369 Application Schematic Cellular Low Noise Amplifier ~881MHz C1 0.1 μF 1 C2 0.1 μF 2 50 Ω μstrip C6 33 nF L3 6.8 nH 3 4 L2 10 nH C3 3 pF 5 Logic Control R1 1.6 kΩ VREF/PD 6 *C7 DNI L1 1.5 nH 50 Ω μstrip SELECT J1 RF IN J2 RF OUT VCC C5 10 nF C4 100 pF * It is recommended added to initial customer PCBA layout for flexibility to optimize performance.
