Modulator Eyes Cable, Satellite And Wireless Apps

The ADL5385 quadrature modulator operates at frequencies from 50 MHz to 2.2 GHz, making it suitable for low IF and RF applications. Requiring just a single-ended, two-times local oscillator input, the device converts modulation information from the baseband to the final RF input. With a dynamic range of +10 dBm P1dB, single-ended output linearity is +24 dBm IP3 and the noise floor is -158 dBm/Hz. The chip specifies a -46 dBm carrier feed-through and -50 dBc sideband suppression at 140 MHz. Available next month in a 24-pin, 4 mm x 4 mm LFCSP, price is $4.98 each/1,000.
