The ADMV8913 is a fully monolithic microwave integrated circuit that that features a digitally selectable frequency of operation. The device has an integrated high-pass filter and an integrated low-pass filter, that allow a pass-band response within the 7 to 12 GHz frequency range.The flexible architecture of the ADMV8913 allows for 3 dB cutoff frequency (f3dB) of the high-pass and the low-pass filter to be controlled independently. The digital logic control on each filter is 4 bits wide (16 states) and controls the on-chip reactive elements to adjust the f3dB. The typical insertion loss is 5 dB, and the wideband rejection is 35 dB, which is ideally suitable for minimizing system harmonics.This tunable filter can be used as a smaller alternative to large switched filter banks and cavity tuned filters, and this device provides a dynamically adjustable solution in advanced communications applications.APPLICATIONSTest and measurement equipmentMilitary radar and electronic warfare/electronic countermeasuresSatellite communicationsIndustrial and medical equipment

The ADN88341 is a monolithic TEC controller with an integrated TEC controller. It has a linear power stage, a pulse-width modulation (PWM) power stage, and two zero-drift, rail-to-rail operational amplifiers. The linear controller works with the PWM driver to control the internal power MOSFETs in an H-bridge configuration. By measuring the thermal sensor feedback voltage and using the integrated operational amplifiers as a proportional integral differential (PID) compensator to condition the signal, the ADN8834 drives current through a TEC to settle the temperature of a laser diode or a passive component attached to the TEC module to the programmed target temperature.The ADN8834 supports negative temperature coefficient (NTC) thermistors as well as positive temperature coefficient (PTC) resistive temperature detectors (RTD). The target temperature is set as an analog voltage input either from a digital-to-analog converter (DAC) or from an external resistor divider.The temperature control loop of the ADN8834 is stabilized by PID compensation utilizing the built in, zero drift chopper amplifiers. The internal 2.50 V reference voltage provides a 1% accurate output that is used to bias a thermistor temperature sensing bridge as well as a voltage divider network to program the maximum TEC current and voltage limits for both the heating and cooling modes. With the zero drift chopper amplifiers, extremely good long-term temperature stability is maintained via an autonomous analog temperature control loop.APPLICATIONS TEC temperature control Optical modules Optical fiber amplifiers Optical networking systems Instruments requiring TEC temperature control1 Product is covered by U.S. Patent No. 6,486,643.
