   The RF2321 is a general purpose, low-cost silicon amplifier designed for operation from a 3V supply. The circuit configuration with resistive feedback allows for broadband cascadable amplification. Capacitive compensation extends the bandwidth of the amplifier and input stage design optimizes noise figure. The device is unconditionally stable and internally matched to 50 Ω. The only external components required for specified performance are bypass and DC blocking capacitors (as shown in application schematic). The RF2321 is available in a very small industry-standard SOT-23 5-lead surface mount package, enabling compact designs which conserve board space. .071 .059 .020 .014 .122 .106 1 4 .004 .000 .083 .067 .118 .102 .051 .039 .008 MIN .010 .004

Keep traces physically short and connect immediately to ground plane for best performance. Same as pin 1. RF input pin. This pin is not internally DC blocked and thus requires an external blocking capacitor suitable for the frequency of operation.

Because DC biasing is present on this pin, a DC blocking capacitor should be used in most applications (see application schematic).
