RTC6655F : 2.4/5 GHz Dual Band Antenna Switch Module
The RTC6655F is an integrated antenna switch module designed for 802.11a/b/g/n WLAN applications.
This device consists of a SPDT switch (SW) and two diplexers (DIPXs). The module is designed to
operate in 2.4 and 5 GHz ISM band, compatible with 802.11a/b/g/n wireless LAN system with low loss,
high isolation and high out-band suppression. The diplexer consists of two pass band responses in both
onfidentialtransmitting and receiving paths with 50 ohm impedance matching. For transmit path, the in-band
insertion loss is smaller than 1.6 dB at 2.4 GHz-band and 1.9 dB at 5GHz-band while keeping return loss
higher than 11 dB. For receive path, the in-band insertion loss is smaller than 1.5 dB at 2.4 GHz-band and
1.8 dB at 5 GHz-band while keeping return loss higher than 10 dB. The isolation between transmit and
receive path is typically higher than 22 dB.
The RTC6655F is packaged in a tiny industry-standard 16-lead surface mount package QFN 3 mm X 3
mm with lead-free RoHS/Halogen Free compliant.
