pin FuncTions GND (Pins 8, 17, 23, Exposed Pad Pin 25):
Ground. For
FDBK (Pin 19):
A feedback capacitor is required between best RF performance, all ground pins should be connected OUT (Pin 18) and the FDBK pin to ensure good matching to the printed circuit board ground plane. The exposed pad and gain flatness at low frequencies. should have multiple via holes to an underlying ground
OUT (Pin 18):
Amplifier Output Pin. A choke inductor is plane for low inductance and good thermal dissipation. necessary to provide power from the 5V supply and to
IN (Pin 24):
Signal Input Pin. This pin has an internally provide RF isolation. For best performance select a choke generated 2V DC bias. A DC blocking capacitor is required. with low DC loss and high self-resonant frequency (SRF). See the Applications Information section for specific A DC blocking capacitor is also required. See the Applica- recommendations. tions Information section for specific recommendations.
VCC (Pins 9, 22):
Positive Power Supply. Either VCC pin
DNC (Pins 1 to 5, 7, 10 to 14, 16, 20, 21):
Do Not Connect. should be connected to the 5V supply. Bypass the VCC pin Do not connect these pins; allow them to

should be physically close to the package. Pins 9 and 22
T_DIODE (Pin 15):
Optional Diode. The T_DIODE can be for- are internally connected within the package ward-biased to ground with 1mA of current. The measured
NFILT (Pins 6):
Noise Filter Capacitor. A capacitor to GND voltage will be an indicator of chip temperature. is required to reduce low frequency noise.
