Skyworks' WLAN front-end module family supports the 802.11a, b and g wireless LAN standards both individually and in the combinations of 802.11b/g and 802.11a/b/g. The frequencies of operation include 2.4 to 2.5 GHz and 4.9 to 5.85 GHz and support complementary code keying (CCK) for 802.11b and orthogonal frequency division multiplexing (OFDM) for 802.11a/g up to 64 quadrature amplitude modulation (64QAM). The 802.11 WLAN front-end module include five products. The SKY65200 WLAN 802.11a/b/g module features two HBT PAs with built-in power detection capabilities, a diversity switch manufactured in a GaAs PHEMT process, plus two highly integrated low-temperature co-fired ceramics (LTCC) components a low-loss band-pass filter for receive filtering and a dual diplexer, which incorporates two high-band and low-band diplexers into a single component. The SKY65202 WLAN 802.11a module includes an HBT PA, band pass and low pass filtering, and a diversity switch manufactured in a GaAs PHEMT process. The device meets linearity requirements of up to 15 dBm of output power to the antenna, and is offered in an 8 × 10 × 1.7 mm package. The SKY65203 WLAN 802.11b/g module includes a single-ended HBT PA, and low pass filtering for transmit, a diversity switch manufactured in a GaAs PHEMT process and a bandpass filter and balanced output for receive. The device meets linearity requirements of up to 21 dBm at the antenna for 802.11b and 16 dBm for 802.11g and is offered in an 8 × 10 × 1.7 mm package. The SKY65204 WLAN 802.11b/g module for low-cost applications meets the same high linearity requirements as the SKY65203 and SKY65201, but replaces the diversity switch with individual transmit/receive (T/R) and antenna switches, and is offered in a 6 × 6 × 1.7 mm package. The SKY65205 WLAN 802.11b/g module maintains the same performance as the SKY65204 but includes balanced receive port functionality, and is available in a 6 × 6 × 1.4 mm package.
