... Distortion performance of –63 dBc is achieved with an output level dBmV at 21 MHz bandwidth. A key performance and cost advantage of the AD8327 results from the ability to maintain a constant 75 Ω output impedance during Transmit Enable and Transmit Disable conditions. In addition, this device has a sleep mode function that reduces the quiescent current ...

Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8327 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges ...

... The serial interface timing for the AD8327 is shown in Figures 2 and 3. The programmable gain range of the AD8327 is –18. +30 dB with steps of 6.02 dB per major carry. This provides a total gain range of 48.16 dB. The AD8327 was characterized with a TOKO transformer (TOKO#617DB-A0070) on the input, and the stated gain values account for the losses due to the transformer ...

... R13, or calculate other input configurations using the equation in Figure Output Bias, Impedance, and Termination The output of the AD8327 has a dc bias level of approximately V /2; therefore, it should be ac-coupled before being applied to CC the load. The output impedance of the AD8327 is internally maintained at 75 Ω, regardless of whether the amplifier is in transmit enable or transmit disable mode ...

... PC. A standard printer cable connected between the parallel port of the personal com- puter is used to feed all the necessary data to the AD8327 using the Windows-based control software. This package provides a means of evaluating the amplifier with a convenient way to program the gain/attenuation, as well as offering easy control of the asynchronous TXEN and SLEEP pins ...

... AD8327 Transmit Enable and Sleep Mode The Transmit Enable and Transmit Disable buttons select the mode of operation of the AD8327 by asserting logic levels on the asynchronous TXEN pin. The Transmit Disable button applies Logic 0 to the TXEN pin, disabling forward transmis- sion while maintaining a 75 Ω back termination. The Transmit Enable button applies Logic 1 to the TXEN pin, enabling the AD8327 for forward transmission. Checking the “ ...
