. . . designed for high–gain, low–noise amplifier oscillator and mixer applica­tions. Specifically packaged for thick and thin–film circuits using surface mount components.
High Gain — Gpe = 17 dB Typ @ f = 450 MHz
Low Noise — NF = 3.0 dB Typ @ f = 450 MHz
Available in tape and reel packaging options by adding suffix:
T1 suffix = 3,000 units per reel T3 suffix = 10,000 units per reel
