ALM-38140 50MHz – 4GHz PIN Diode Variable Attenuator Module Data Sheet Description Features 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. • Fully integrated module 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. • Low phase shift performance 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. Typical Performance at 1.9GHz ALM-38140 is ideal for gain control in RF amplifier circuits. • Excellent Input IP3 performance • High Input P1dB compression • Tape-and-Reel packaging option available Specifications • Attenuation : 39dB • Insertion Loss : 3.2dB • Input IP3 : 50dBm • Input P1dB : > 30dBm Applications • Broadband system applications; such as CATV, WCDMA, VSAT, WIMAX, Cellular base station. Linput Loutput Vcontrol Package Marking 38140 WWYY XXXX • High dynamic range • General purpose voltage controlled attenuator for low current applications. • Temperature compensation circuitry RF 2 GND RF 1 • Automatic Gain Control Vsupply Top View Bottom View Note: Package marking provides orientation and identification “38140” = Device Part Number “WWYY” = Work week and year of manufacture “XXXX” = Last 4 digit of assembly lot number * RF1 and RF2 can be used either as RF input or RF output as they are symmetrical.

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. 12 Package Dimension Drawing 1.05±0.10 0.70 2x 0.60 0.07 all gaps 0.60 C'fer 45°x0.4 0.16 38140 WWYY XXXX 0.73-4x 0.80-4x 0.40 sq-6x 1.90-2x 3.80±0.10 0.70 1.30-4x 3.80±0.10 1.30-2x 1.90-4x Top View Side View Note : Note : 1.
