0.6-1.0GHz ¼W Digital Variable Gain Amplifier
PC Board Layout
Top RF layer is .014” NELCO N4000-13 material, є
4 total layers (0.062” thick) for mechanical rigidity. Metal layers are 1-
oz copper. Microstrip line details: width = .030”, spacing = .036”.
The pad pattern shown has been developed and tested for optimized
assembly at TriQuint Semiconductor. The PCB land pattern has been
developed to accommodate lead and package tolerances. Since surface
mount processes vary from supplier to supplier, careful process
development is recommended.

Description
Serial Latch Enable Input. When LE is high, latch is clear and content of SPI control the attenuator.
When LE is low, data in SPI is latched.
Serial data input. The data and clock pins allow the data to be entered serially into SPI and is
independent of Latch state.
Serial clock input.
No connect or open. This pin is not connected in this module
Input, matched to 50 ohms. Internally DC blocked.
Supply Voltage to AMP1. This pin is connected internally to 2 bypass capacitors (100 pF, 0.1 uF)
followed by a 68 nH inductor inside the module.
Supply Voltage to AMP2. This pin is connected internally to 2 bypass capacitors (100 pF, 0.1 uF)
followed by a 47 nH inductor inside the module.
Output matched to 50 ohms. Internally DC blocked.
Supply voltage for SPI and DSA chip. This pin is connected to 0.1 uF bypass capacitor internally.
