Analog Devices, Inc. (ADI) has made available its ADL5324 half-Watt RF driver amplifier that operates over a temperature range of -40° C to +105° C and features an adjustable bias allowing RF designers to set the driver’s power consumption to the performance needs of the system, without the need for a bias resistor. The company states ADL5324 RF driver amplifier is well-suited for wired and wireless applications including cellular infrastructure, industrial, science, and medical (ISM) band power amplifiers, and defense and instrumentation equipment. Key Features:
adjustable bias to tailor driver performance from 3.3-V to 5-V with a variable or fixed supply; no bias resistor needed
power consumption of 62 mA on 3.3 V, up to 133 mA on 5 V, which can be biased anywhere in between these two points
frequency range of 400 MHz to 4000 MHz
operation over temperature range of -40°C to +105°C
performance: OIP3 of 43 dBm, a P1dB of 29 dBm, a gain of 14.6 dB, and a noise figure of 3.8 dB at 2140 MHz
electrostatic discharge (ESD) rating of Class 2, ± 3 kV
available in the SOT-89 package
The ADL5324 is sampling and in full production now. Pricing is $3.35 each in 1,000 quantities.
