The Broadcom BCM2050 is a 2.4 GHz radio-on-a-chip (RoC). It was part of an early 802.11g chipset, paired with the BCM4306 baseband processor.
Key features and specifications:
- Wireless Standard: Supports the IEEE 802.11g draft standard (54G) with a maximum data rate of 54 Mbps, while also being backward compatible with 802.11b devices (11 Mbps).
- Modulation Techniques: Utilizes OFDM in 802.11g mode and CCK, DQPSK, and DBPSK in 802.11b mode.
- Operating Frequency: Operates in the 2.4 - 2.497 GHz range.
- Security: Supports hardware encryption, including 128-bit WEP and hardware AES, which supports WPA, CCM, OCB, and 802.11i.
- Typical Specifications:
- Noise Figure (NF): 4 dB typ
- Receiver IIP3 (max. gain): -16 dBm typ
- Receiver IIP3 (min. gain): 4 dBm typ
- Transmitter output power: 5 dBm typ
- Transmitter OIP3: 18 dBm
- Transmit-mode current consumption: 80 mA typ. (at 1.8 V)
- Receive-mode current consumption: 110 mA typ. (at 1.8 V)
- Supply Voltage (Vdd): 1.8 V
Applications and Compatibility: The BCM2050 was used in various devices, particularly in conjunction with other Broadcom chips for wireless networking applications. For example, it was paired with the BCM5352EL in the BCM95352ELGR reference design, a system-on-a-chip for 802.11g routers. It was also used with the BCM4306 Baseband Processor in early 802.11g chipsets. Note: The BCM2050 is a component of older wireless technologies. Broadcom, now Broadcom Inc., has since developed newer and more advanced wireless solutions, including Wi-Fi 5 (802.11ac) and beyond.
