5-bit digital attenuator with a 0.5 dB minimum step
size and 15.5 dB total attenuation. The design has
been optimized to minimize phase variation over the
attenuation range. This attenuator and integral TTL
driver is in a hermetically sealed ceramic 16-lead
surface mount package. The MAAD-009195-000100
is ideally suited for use where accuracy, fast
switching, very low power consumption and low
intermodulation products are required. Typical
applications include dynamic range setting in
precision receiver circuits and other gain / leveling
control circuits. Environmental screening is
available. Contact the factory for information.

2. Maximum input power is specified with power applied to RF1. If power is applied to RF2, then maximum operating power is +16 dBm.
3. This attenuator is guaranteed monotonic.
4. 1 dB Compression was measured up to +26 dBm, which is the absolute maximum rating for this device.
