ADRV9002 vs ADRV9009


Post by IB4TL »

The ADRV series of chips from Analog Devices are used in many software-defined radio platforms. With built-in dual transceivers they enable a range of functionality that’s not possible with other lower priced SDRs.

In this post we look at the main differences between the ADRV9002 and ADRV9009. In an earlier post we compared the ADRV9002 and the ADRV9004

Let’s get into the details.
Summary Table
This table summarizes the specifications of the two products.

As can be seen from the table, there are many differences.
Differences between ADRV9002 and ADRV9009 Frequency range
The ADRV9002 covers a wider frequency range – at the lower end going down to 30 MHz.
IF Bandwidth
This is where the biggest difference is between the two chips is. With 200 MHz bandwidth, the ADRV9009 is better suited to new wireless systems such as 802.11ax, Wi-Fi 6, and 5G. The ADRV9002 cannot process signals wider than 40 MHz and is good for older systems such as 4G.
The ADRV9002 has better linearity specifications – both on the receive as well as the transmit signal path.
Digital Pre-Distortion (DPD) Linearization
The ADRV9002 has this capability and as a result is better suited for signal transmission.
What does DPD do?
The Digital Pre-Distortion function compensates for non-linearities in the response of the Transmit Power Amplifier. The result is a linear output from the PA.
What is the benefit of DPD?
The DPD capability allows the transceiver to drive the PA closer to saturation. This facilitates a higher efficiency power amplifier while maintaining linearity.
Power consumption
The max power consumption of the ADRV9009 is 5.7 Watt

The max power consumption of the ADRV9002 is 2.8 Watt
ADRV9002 or ADRV9009 – Which one should I pick?
If your application bandwidth is restricted to 40 MHz, then the ADRV9002 is the better choice – as it has better RF specifications. However, if you have to process wideband signals – like 5G for instance, then the ADRV9009 is the one.
