See our web site for RoHS Compliance methodologies and qualifications. Typical Applications • Base Station Infrastructure • Portable Wireless • CATV & DBS • MMDS & Wireless LAN • Band switch • Diplexer switches • Bypass switches General Description The HSWA2-30DR+ is a 50Ω high isolation SPDT RF switch designed for wireless applications, covering a broad frequency range from DC up to 3GHz with low insertion loss. The HSWA2-30DR+ operates on a single supply voltage +3V. See application note AN-80-006 for +5V supply voltage. This unit includes an internal CMOS control driver with two-pins control. The switch consumes very low supply current, 8 μA typ. The HSWA2-30DR+ switch is in a very small size and low profile package, 4x4mm and 0.9mm respectively.

RF3 and RF4 SMA 50Ω connectors are connected through a 50Ω transmission line that is used to estimate the evaluation board loss for de-embedding purposes. The transmission lines were designed using a coplanar waveguide with ground plane. For details, please see suggested PCB layout on Page 8. The number of vias surrounding the switch is critical for obtaining the specified isolation. The TB-347 operates from +2.7V to +6.5V applied to VDD connector. IC1 voltage regulator limits the supply voltage to the switch to +3.3V. IC2 is a Schmitt trigger & buffer which prevents an overload of switch control inputs from high level control signals (up to +5.5V) and prevents from noise and transient spikes during switching process. The control connector is used for computer control mode or manual operation mode. In manual control mode connect Control 1 and/or Control 2 to ground to set Control 1 and/or Control 2 to logic low, respectively. When jumpers are removed, the digital control input pulled up to VDD for logic high. For computer control mode the software & cable are supplied. The cable should be connected between computer LPT port and evaluation board control connector.
