BCM4330 Preliminary Data Sheet
WLAN RF Specifications
Section 19: WLAN RF Specifications
Introduction
The BCM4330 includes an integrated dual-band direct conversion radio that supports either the 2.4 GHz band
or the 5 GHz band. The BCM4330 does not provide simultaneous 2.4 GHz and 5 GHz operation. This section
describes the RF characteristics of the 2.4 GHz and 5 GHz portions of the radio.
Note: Values in this data sheet are design goals and are subject to change based on the results of device
characterization.
Unless otherwise stated, limit values apply for the conditions specified inTable 25: “Environmental Ratings,” on
page 118 and Table 27: “Recommended Operating Conditions and DC Characteristics,” on page 119. Typical
values apply for the following conditions:
• Vbatt = 3.6V
• Ambient temperature +25°C
