1. Above reference insertion loss.
2. All specifications apply when operated with bias voltages of +5V for V_CC and –5.0 V to –8.0 V for V_EE and 50Ω impedance at all ports
unless otherwise stated.
3. This attenuator is guaranteed monotonic.
4. For the attenuator to meet the guaranteed specifications, it is necessary to have a DC return on either RF1 or RF2. The DC return can be
either a 10KΩ resistor, or an RF choke.
5. V_EE = -5 V for the typical numbers given.

6. Exceeding any one or combination of these limits may cause
permanent damage to this device.
7. M/A-COM does not recommend sustained operation near
these survivability limits.
8. Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
