External RF and IF bypassing is required. The trace length between the pin and the bypass capacitors should be mini- mized. The ground side of the bypass capacitors should connect immedi- ately to ground plane. This pin connects to pin 8 through a 150Ω resistor. This allows for simple biasing of the collector at pin 6. Refer to Application Schematics 1 and 3. 2G N D 1 Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. 3R F I N RF input pin. This pin is internally DC-blocked and matched to 50Ω for fre- quencies above 1GHz. When using below 1GHz, it is recommended that this pin be matched with series inductance to series-resonate out the inter- nal blocking capacitor. Refer to Application Schematics 1 and 2. 4G N D 2 Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. 5N C No connection. This pin is typically left unconnected or grounded. 6R F O U T LNA Output pin. This pin is an open-collector output. It must be biased to either VCC or pin 8 through a choke or matching inductor. This pin is typi- cally matched to 50Ω with a shunt bias/matching inductor and series blocking/matching capacitor. Refer to application schematics. See pin 3. 7N C No connection. This pin is typically left unconnected or grounded. 8V C C 2 Optional power supply connection for biasing pin 6. This pin connects to pin 1 through a 150Ω resistor. This allows for simple biasing of the collec- tor at pin 6. When used, this pin should be RF bypassed. Refer to Applica- tion Schematics 1 and 3.
