SMT device painlessly performs 1-GHz splits
By Bill Schweber -- EDN, May 26, 2005
Set-top boxes driving multiple tuners need to split the input signal; the Anadigics APS3604 active splitter simplifies the task (Picture). This device, with a 75Ω balanced RF input, accepts 50-MHz to 1-GHz signals and yields three balanced RF outputs. The 5V unit has a typical noise figure of 4.8 dB and maximum gain of 5 dB, thus eliminating the need for separate front-end gain at the tuner. Typical current consumption is 175 mA for this $3.90 (1000) product.
