The ADL5324 incorporates a dynamically adjustable biasing The ADL5324 also delivers excel ent ACPR vs. output power and circuit that al ows for the customization of OIP3 and P1dB bias voltage. The driver can deliver greater than 17 dBm of output performance from 3.3 V to 5 V, without the need for an external power at 2140 MHz, while achieving an ACPR of −55 dBc at 5 V. If bias resistor. This feature gives the designer the ability to tailor the bias is reduced to 3.3 V, the −55 dBc ACPR output power driver amplifier performance to the specific needs of the design. only minimally reduces to 15 dBm.
