Richardson has released a 1/2 W RF driver amplifier from Analog Devices.
The ADL5324 incorporates a dynamically adjustable biasing circuit that allows for the customisation of OIP3 and P1 dB performance from 3.3 to 5 V, without the need for an external bias resistor.
This creates the opportunity for dynamic biasing of the device where a variable supply is used to allow for full 5 V biasing under large signal conditions and then reduced supply voltage when signal levels are smaller and lower power consumption is desirable.
The amplifier covers the frequency range of 400 to 4000 MHz and requires few external components to be tuned to a specific band.
Additional features include: gain of 14.6 dB at 2140 MHz; OIP3 of 43.1 dBm at 2140 MHz; P1 dB of 29.1 dBm at 2140 MHz; noise figure of 3.8 dB; SOT-89 package, MSL-1 rated; ESD rating of ±3 kV (Class 2).
