The ADF5709 wideband, monolithic microwave integrated circuit (MMIC), voltage controlled oscillator (VCO) supports an output frequency (fOUT) range of 9.85 GHz to 20.5 GHz while maintaining ?83 dBc/Hz phase noise at 100 kHz offset without subharmonic tones. The wide frequency tuning range and low phase noise allow phase-locked loop (PLL) solutions for a variety of frequency bands and limit the need for multiple narrow-band VCOs. The broad frequency coverage reduces the board design complexity and simplifies the bill of materials when designing RF and microwave applications.The VCO operates from a single 5 V supply and consumes only 70 mA of supply current that results in minimal power dissipation. The ADF5709 low power consumption is ideal for high performance applications with limited or no airflow. The monolithic construction of the VCO allows optimal output power and noise characteristics over temperature variations.The VCO is fully integrated and incorporates a resonator, a negative resistance device, and a varactor diode that minimize the number of external components and reduces board space.The low input impedance on the VTUNE pin of the ADF5709 enables high tuning speed and modulation bandwidth, which allows faster frequency sweeps and lock times when used as part of a frequency synthesizer, for example, in radar or in test and measurement applications.The ADF5709 is encapsulated into a tiny, 3.90 mm ? 3.90 mm, RoHS compliant, ceramic leadless chip carrier (LCC) package. The package includes through vias to the exposed pad, enhancing thermal characteristics.The small size, optimal noise performance, low power consumption, and wide tuning range of the ADF5709 make the device ideal for many applications requiring flexibility, high performance, a small footprint, and a tight power budget. The ADF5709 is pin to pin compatible with the HMC733 and other Analog Devices, Inc., wideband VCOs.APPLICATIONSIndustrial and medical equipmentTest and measurement equipmentMilitary radars, electronic warfare (EW), and electronic countermeasures (ECMs)Point to point and multipoint radiosVery small aperture terminals (VSATs)Wireless communication infrastructure

The AD608 provides a low power, low distortion, low noise mixer as well as a complete, monolithic logarithmic/limiting amplifier that uses a successive-detection technique. In addition, the AD608 provides both a high speed received signal strength indicator (RSSI) output with 80 dB dynamic range and a hard-limited output. The RSSI output is from a two-pole postdemodulation low-pass filter and provides a loadable output voltage of 0.2 V to 1.8 V. The AD608 operates from a single 2.7 V to 5.5 V supply at a typical power level of 21 mW at 3 V.The RF and local oscillator (LO) bandwidths both exceed 500 MHz. In a typical IF application, the AD608 can accept the output of a 240 MHz surface acoustic wave (SAW) filter and down-convert it to a nominal 10.7 MHz IF with a conversion gain of 24 dB (ZIF = 165 ?). The AD608 logarithmic/limiting amplifier section handles any IF from low frequency (LF) up to 30 MHz.The mixer is a doubly balanced gilbert-cell mixer and operates linearly for RF inputs spanning ?95 dBm to ?15 dBm. It has a nominal ?5 dBm third-order intercept. An on-board LO preamplifier requires only ?16 dBm of LO drive. The current output of the mixer drives a reverse-terminated, industry-standard 10.7 MHz, 330 ? filter.The nominal logarithmic scaling is such that the output is +0.2 V for a sinusoidal input to the IF amplifier of ?75 dBm and +1.8 V at an input of +5 dBm; over this range, the logarithmic conformance is typically ?1 dB. The logarithmic slope is proportional to the supply voltage. A feedback loop automatically nulls the input offset of the first stage down to the submicrovolt level.The AD608 limiter output provides a hard-limited signal output at 400 mV p-p. The voltage gain of the limiting amplifier to this output is more than 100 dB. Transition times are 11 ns and the phase is stable to within ?3? at 10.7 MHz for signals from ?75 dBm to +5 dBm.The AD608 is enabled by a CMOS logic-level voltage input, with a response time of 200 ns. When disabled, the standby power is reduced to 300 ?W within 400 ns.The AD608 is specified for the industrial temperature range of ?25?C to +85?C for 2.7 V to 5.5 V supplies and ?40?C to +85?C for 3.0 V to 5.5 V supplies. This device comes in a 16-lead plastic SOIC.APPLICATIONS PHS, GSM, TDMA, FM, or PM receivers Battery-powered instrumentation Base station RSSI measurements

The LTC5544 is part of a family of high dynamic range, high gain passive downconverting mixers covering the 600MHz to 6GHz frequency range. The LTC5544 is optimized for 4GHz to 6GHz RF applications. The LO frequency must fall within the 4.2GHz to 5.8GHz range for optimum performance. A typical application is a WiMAX receiver with a 5.15GHz to 5.35GHz RF input and low side LO.The LTC5544 is designed for 3.3V operation, however; the IF amplifier can be powered with 5V for the higher P1dB.The LTC5544?s high level of integration minimizes the total solution cost, board space and system-level variation, while providing the highest dynamic range for demanding receiver applications.Applications 5GHz WiMAX/WLAN Receiver 4.9GHz Public Safety Bands 4.9GHz to 6GHz Military Communications Point-to-Point Broadband Communications Radar Systems
