Description

Insertion loss is an important index for switch performance. Switch modules using the conventional LTCC* substrate adopted a structure in which the frequency band was divided into a low band (900 MHz band) and a high band (1800/1900 MHz band) using a diplexer, and after that, the path switches were connected. (See figure 1.) The switch structure adopted by Sony in these prod- ucts is the SP7T structure. A low-pass filter is inserted in the GSM Tx path. (See figure 2.) In the conventional LTCC mod- ule structure, the insertion loss for all of the paths was the sum of the diplexer and the path switches themselves. As a result, the overall loss was quite large. In contrast, in the SP7T structure, only the switch insertion loss occurs in the paths

Applications

Negative Power Supply, specified for opera- tion from 0 V to C2.7 V. Terminal B of RDAC#2. Terminal A of RDAC#2. Wiper, RDAC#2, addr = 12 Digital Ground. Active Low Input. Terminal A open-circuit and Terminal B shorted to Wiper. Shut- down controls both RDACs #1 and #2. Chip Select Input, Active Low. When CS returns high, data in the serial input register is decoded, based on the address bit, and loaded into the corresponding RDAC register. Serial Data Input. MSB is loaded first. Serial Data Output. Open Drain transistor requires pull-up resistor. Serial Clock Input. Positive Edge Triggered. Positive Power Supply. Specified for opera- tion at 2.7 V to 5.5 V. Wiper, RDAC #1, addr = 02. Terminal A of RDAC #1. Terminal B of RDAC #1.
 

Features

Like all capacitance sensors, the CTV222 relies on Kirchoffs Current Law (Figure 1-5) to detect the change in capacitance of the electrode. This law as applied to capacitive sensing requires that the sensors field current must complete a loop, returning back to its source in order for capacitance to be sensed. Although most designers relate to Kirchoffs law with regard to hardwired circuits, it applies equally to capacitive field flows. By implication it requires that the signal ground and the target object must both be coupled together in some manner for a capacitive sensor to operate properly. Note that there is no need to provide actual hardwired ground connections; capacitive coupling to ground (Cx1) is always sufficient, even if the coupling might seem very tenuous. For example, powering the sensor via an isolated transformer will provide ample ground coupling, since there is capacitance between the windings and/or the transformer core, and from the power wiring itself directly to 'local earth'.
