ALM-38140
50MHz - 4GHz PIN Diode Variable Attenuator Module
Data Sheet
Description
Avago Technologies' ALM-38140 is a fully matched wideband variable attenuator module with high linearity performance and high dynamic range. The high dynamic range and low phase shift can be achieved with only one external inductor place between Linput and Loutput. ALM-38140 is a fully integrated solution using Avago Technologies' low distortion silicon PIN diodes housed in a miniature 3.8 x 3.8 x 1.0 mm3 MCOB (Multiple-Chips-OnBoard) package. This variable attenuator module is easily operated with a constant voltage, Vsupply = 2.7V and a control voltage, Vcontrol = 0.8 - 5V. No external biasing components needed. ALM-38140 is ideal for gain control in RF amplifier circuits.

Figure 34. Demo board Layout
Notes: 1. PCB material used is 10 mils Rogers RO4350, with FR4 backing for mechanical strength. 2. The phase compensation coil values given in Table 1 are based on the trace layout on demo board shown in Figure 33. Trace layout different from that specified in Figure 33, will require different values for the phase compensation coil. 3. Pad layout for phase compensation coil shown in Figure 33 is based on 0402 size.
