The ADRF5026 is a nonreflective, single-pole, double-throw (SPDT) radio frequency (RF) switch manufactured in a silicon process.The ADRF5026 operates from 100 MHz to 44 GHz with better than 3.8 dB of insertion loss and 45 dB of isolation. The ADRF5026 features an all off control, where both RF ports are in an isolation state. The ADRF5026 has a nonreflective design and both of the RF ports are internally terminated to 50 ?. The ADRF5026 requires a dual-supply voltage of +3.3 V and ?3.3 V. The device employs complimentary metal-oxide semiconductor/low-voltage transistor-transistor logic (CMOS/LVTTL) logic-compatible controls.The ADRF5026 is pin-compatible with the ADRF5027 low frequency cutoff version, which operates from 9 kHz to 44 GHz. The ADRF5026 RF ports are designed to match a characteristic impedance of 50 ?. For ultrawideband products, impedance matching on the RF transmission lines can further optimize high frequency insertion loss and return loss characteristics.

The LT6236/LT6237/LT6238 are single/dual/quad low noise, rail-to-rail output op amps that feature 1.1nV/?Hz input referred noise voltage density and draw only 3.5mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 215MHz gain bandwidth product and a 70V/?s slew rate. Low noise, fast settling time and low offset voltage make this amplifier optimal to drive low noise, high speed SAR ADCs. The LT6236 includes a shutdown feature that can be used to reduce the supply current to less than 10?A.This amplifier family has an output that swings within 50mV of either supply rail to maximize the signal dynamic range in low supply applications and is specified on 3.3V, 5V and ?5V supplies.The LT6236/LT6237/LT6238 are upgrades to the LT6230/LT6231/LT6232, offering similar performance with reduced wideband noise beyond 100kHz.Applications 16-Bit and 18-Bit SAR ADC Drivers Active Filters Low Noise, Low Power Signal Processing

The LT6106 is a versatile high side current sense amplifier. Design flexibility is provided by the excellent device characteristics: 250?V maximum offset and 40nA maximum input bias current. Gain for each device is set by two resistors and allows for accuracy better than 1%.The LT6106 monitors current via the voltage across an external sense resistor (shunt resistor). Internal circuitry converts input voltage to output current, allowing for a small sense signal on a high common mode voltage to be translated into a ground referenced signal. The low DC offset allows for monitoring very small sense voltages. As a result, a small valued shunt resistor can be used, which minimizes the power loss in the shunt.The wide 2.7V to 44V input voltage range, high accuracy and wide operating temperature range make the LT6106 ideal for automotive, industrial and power management applications. The very low power supply current of the LT6106 also makes it suitable for low power and battery operated applications.Applications Current Shunt Measurement Battery Monitoring Power Management Motor Control Lamp Monitoring Overcurrent and Fault Detection

The ADL5240 is a high performance, digitally controlled variable gain amplifier (VGA) operating from 100 MHz to 4000 MHz. The VGA integrates a high performance, 20 dB gain, internally matched amplifier (AMP) with a 6-bit digital step attenuator (DSA) that has a gain control range of 31.5 dB in 0.5 dB steps with ?0.25 dB step accuracy. The attenuation of the DSA can be controlled using a serial or parallel interface.Both the gain block and DSA are internally matched to 50 ? at their inputs and outputs and are separately biased. The separate bias allows all or part of the ADL5240 to be used, which facilitates easy reuse throughout a design. The pinout of the ADL5240 also enables either the gain block or DSA to be first, giving the VGA maximum flexibility in a signal chain.The ADL5240 consumes just 93 mA and operates from a single supply ranging from 4.75 V to 5.25 V. The VGA is packaged in a thermally efficient, 5 mm ? 5 mm, 32-lead LFCSP and is fully specified for operation from ?40?C to +85?C.
