IWR1443: IF bandwidth question

Francois Charlot

Part Number: IWR1443
Other Parts Discussed in Thread: AWR1443, AWR1243, AWR1642, IWR1642

Hello,

In the IWR1443 datasheet, table 5.7 "RF specifications" lists and IF bandwidth of 5 MHz and real sampling rate of 12.5 Msps, when in other places (e.g., sections 3.1 and 6.4.1.3) give 15 MHz and 37.5 Msps. Could you confirm the latter figures are correct and the former, a typo?

Thank you,
François.

Hello Francois,

The IWR1443 shares the same bandwidth as the AWR1243. The AWR1443 lists the lower bandwidth.

This is being updated in the revised IWR1443 datasheet.

Section 5.7 Max IF bandwidth 15Mhz,

A2D sampling rate (real) 37.5 Msps

A2D sampling rate (complex) 18.75 Msps

Here is a general table (Table 3-1 datasheets)

device	real sample rate (Msps)	complex sample rate 1x (Msps)	max beat frequency (Mhz)
AWR1243	37.5	18.75	15
AWR1443	12.5	6.25	5
IWR1443	37.5	18.75	15
AWR1642	12.5	6.25	5
IWR1642	12.5	6.25	5
