PNP EPITAXIAL TYPE (SWITCHING, INVERTER CIRCUIT, INTERFACE CIRCUIT AND DRIVER CIRCUIT APPLICATIONS)

Switching, Inverter Circuit, Interface Circuit And Driver Circuit Applications • High current type (IC(MAX) = −800mA) • With built-in bias resistors • Simplify circuit design • Reduce a quantity of parts and manufacturing process • Low VCE (sat) • Complementary to RN1421~RN1427

2.45 GHz low voltage RF transceiver

DESCRIPTION The SA2421 transceiver is a combined low–noise amplifier, receive mixer, transmit mixer and LO buffer IC designed using a 20 GHz fT BiCMOS process, QUBiC2, for high–performance low–power communication systems for 2.4–2.5 GHz applications. The LNA has a 3.2 dB noise figure at 2.45 GHz
