How to use evaluation Board TB-347
TB-347
The Evaluation board TB-347 was designed to evaluate the electrical performance of the HSWA2-30DR+ SPDT switch. RF3 and RF4 SMA 50 connectors are connected through a 50 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.
