CYW4343X
16. WLAN RF Specifications
The CYW4343X includes an integrated direct conversion radio that supports the 2.4 GHz band. This section describes the RF char-
acteristics of the 2.4 GHz radio.
Note: Values in this data sheet are design goals and may change based on device characterization results.
Unless otherwise stated, the specifications in this section apply when the operating conditions are within the limits specified in
Table 28, “Environmental Ratings,” on page 90 and Table 30, “Recommended Operating Conditions and DC Characteristics,” on
page 91. Functional operation outside these limits is not guaranteed.
Typical values apply for the following conditions:
■
VBAT = 3.6V.
■
Ambient temperature +25°C.
