100 MHz to 4000 MHz  
RF/IF Digitally Controlled VGA  
Data Sheet  
ADL5243  
FEATURES  
GENERAL DESCRIPTION  
Operating frequency from 100 MHz to 4000 MHz  
Digitally controlled VGA with serial and parallel interfaces  
6-bit, 0.5 dB digital step attenuator  
31.5 dB gain control range with 0.25 dB step accuracy  
Gain Block Amplifier 1  
Gain: 19.2 dB at 2140 MHz  
OIP3: 40.2 dBm at 2140 MHz  
P1dB: 19.8 dBm at 2140 MHz  
Noise figure: 2.9 dB at 2140 MHz  
The ADL5243 is a high performance, digitally controlled  
variable gain amplifier operating from 100 MHz to 4000 MHz.  
The VGA integrates two high performance amplifiers and a  
digital step attenuator (DSA). Amplifier 1 (AMP1) is an  
internally matched gain block amplifier with 20 dB gain, and  
Amplifier 2 (AMP2) is a broadband ¼ W driver amplifier. The  
DSA is 6-bit with a 31.5 dB gain control range, 0.5 dB steps, and  
0.25 dB step accuracy. The attenuation of the DSA can be  
controlled using a serial or parallel interface.  
¼ W Driver Amplifier 2  
The gain block and DSA are internally matched to 50 Ω at their  
inputs and outputs, and all three internal devices are separately  
biased. The separate bias allows all or part of the ADL5243 to be  
used, which allows for easy reuse throughout a design. The  
pinout of the ADL5243 also enables the gain block, DSA, or  
¼ W driver amplifier to be first, giving the VGA maximum  
flexibility in a signal chain.  
Gain: 14.2 dB at 2140 MHz  
OIP3: 41.1 dBm at 2140 MHz  
P1dB: 26.0 dBm at 2140 MHz  
Noise figure: 3.7 dB at 2140 MHz  
Gain block, DSA, or ¼ W driver amplifier can be first  
Low quiescent current of 175 mA  
The companion ADL5240 integrates a gain block with DSA  
The ADL5243 consumes 175 mA and operates off a single  
supply ranging from 4.75 V to 5.25 V. The VGA is packaged in a  
thermally efficient, 5 mm × 5 mm, 32-lead LFCSP and is fully  
specified for operation from −40°C to +85°C. A fully populated  
evaluation board is available.
