It is designed to be driven by the tracking generator output of spectrum analyzers. With its gain of 22 dB and 1dB compression point of +22dBm, it can boost the output power of a tracking generator up to 150mW.<\/p>\n<p>The TBMDA1 is ideal to drive near field probes in order to find the sensitive spot of an electronic circuit or to create electric fields up to 50V\/m when driving the TEM Cell TBTC1, 25V\/m when driving the TBTC2 or 18V\/m when driving the TBTC3. Test signals for immunity testing can be CW, AM or PM. Consequently, the TBMDA1 provides built in modulation capability to generate 1kHz AM or PM signals. In PM mode, the TBMDA1 can also generate a 217Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.<\/p>\n<h3>Features<\/h3>\n<ul>\n<li>CW amplifier (modulation off)<\/li>\n<li>1 kHz, 80% AM modulation<\/li>\n<li>1 kHz, 50% duty cycle pulse modulation<\/li>\n<li>217 Hz, 12.5% duty cycle pulse modulation<\/li>\n<\/ul>\n<h3>Specifications<\/h3>\n<p><strong>Input:\u00a0<\/strong>50 Ohm, SMA female<strong><br \/>\nOutput:<\/strong>50 Ohm, SMA female<strong><br \/>\nNominal supply Voltage:<\/strong>5V, typ. 235mA, Mini-USB-B connector<strong><br \/>\nMaximum supply voltage:<\/strong>5.5V<strong><br \/>\nMaximum input power:<\/strong>+9dBm<strong><br \/>\n1dB output compression point @ 40MHz:<\/strong>+21.5dBm<strong><br \/>\n1dB output compression point @ 2 GHz:<\/strong>+22.5dBm<strong><br \/>\n3rd order output intercept point @ 40 MHz:<\/strong>+39dBm<strong><br \/>\n3rd order output intercept point @ 2 GHz:<\/strong>+42dBm<strong><br \/>\nReverse isolation S12:<\/strong>-45dB<strong><br \/>\nNoise Figure:<\/strong>3 \u2026 4 dB<strong><br \/>\nInternal modulation frequency AM:<\/strong>1 kHz\u00a0 \u00b110%<strong><br \/>\nInternal modulation frequencies PM:<\/strong>1 kHz\u00a0 \u00b110%, 217 Hz \u00b120%<strong><br \/>\nDuty cycle, PM:<\/strong>50% \u00b110% @ 1 kHZ; 12.5% \u00b120% @ 217 Hz<\/p>\n<p>&nbsp;<\/p>\n<p><b>Gain: <\/b><\/p>\n<div class=\"table-wrapper\">\n<table>\n<tbody>\n<tr>\n<td width=\"83\">25 MHz<\/td>\n<td width=\"83\">50 MHz<\/td>\n<td width=\"83\">100 MHz<\/td>\n<td width=\"83\">500 MHz<\/td>\n<td width=\"83\">1 GHz<\/td>\n<td width=\"83\">1.5 GHz<\/td>\n<td width=\"83\">2 GHz<\/td>\n<td width=\"83\">2.5 GHz<\/td>\n<td width=\"83\">3 GHz<\/td>\n<\/tr>\n<tr>\n<td width=\"83\">1221.6dB<\/td>\n<td width=\"83\">24.9 dB<\/td>\n<td width=\"83\">25.5 dB<\/td>\n<td width=\"83\">25.6 dB<\/td>\n<td width=\"83\">24.9 dB<\/td>\n<td width=\"83\">24.1 dB<\/td>\n<td width=\"83\">22.2 dB<\/td>\n<td width=\"83\">22.8 dB<\/td>\n<td width=\"83\">25.8 dB<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Application:<\/h3>\n<ul>\n<li>general purpose gain block<\/li>\n<li>signal source for immunity testing, driving near field probes<\/li>\n<li>signal source for immunity testing, driving TEM Cells<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The TBMDA1 modulated wideband driver amplifier is designed in order to create an inexpensive signal source for immunity testing of electronic building blocks and products.
