The SDL WBA3-4-15G28VP22D is an ultra-wideband RF amplifier engineered for high-performance applications spanning 20 kHz to 18 GHz. It delivers up to 23 dB gain below 10 GHz and 18 dB from 10–18 GHz, with ±3 dB ripple in the lower band and ±5 dB in the upper band. The unit excels as a driver for downstream power amplifiers, preamplifier for spectrum analyzers, and modulator driver in fiber-optic systems supporting data rates to 12.5 Gbps. Its fast pulse recovery and compact design suit integration into EMI/EMC test systems, DWDM platforms, and RF instrumentation.
