SKY72310-362LF Spur-Free, 2.1 GHz Single Fractional-N Frequency
Synthesizer
SKYWORKS SKY72310-362LF is a general purpose, broadband amplifier. The device is fabricated from SKYWORKS InGaP HBT process and packaged in a miniature Small Outline Transistor (SOT-89) package. The device’s 50 Ω input and output impedance allow it to be easily cascaded without external impedance matching networks. The typical –3 dB bandwidth of the SKY72310-362LF is 0.1 to 3.0 GHz. The amplifier is also available in a plastic micro-X package (SKY65016-214LF) and an SC-88 package (SKY65016-92LF).
