VMMK-3503
0.5 - 18 GHz Variable Gain Amplifier in SMT Package
Data Sheet
Description
The VMMK-3503 is a small and easy-to-use, broadband,
variable gain amplifier operating in various frequency
bands from 0.5-18 GHz. It is housed in the Avago Tech-
nologies’ industry-leading and revolutionary sub-min-
iature chip scale package (GaAsCap wafer scale leadless
package) which is small and ultra thin yet can be handled
and placed with standard 0402 pick and place assembly
equipment. The VMMK-3503 provides maximum gain of
12 dB with a typical gain range of 23 dB where the gain
control is accessed from the input port by way of a large
value external resistor. It can be operated from 3 V to 5 V
power supply. It is fabricated using Avago Technologies
unique 0.25 μm E-mode PHEMT technology which elimi-
nates the need for negative gate biasing voltage.

S Parameter Measurements
The S parameters are measured on a 300 mm G-S-G
(ground signal ground) printed circuit board substrate.
Calibration is achieved with a series of through, short
and open substrates from which an accurate set of S pa-
rameters is created. The test board is 0.016 inch thickness
RO4350. Grounding of the device is achieved with a single
plated through hole directly under the device. The effect
of this plated through hole is included in the S parameter
measurements and is difficult to de-embed accurately.
Since the maximum recommended printed circuit board
thickness is nominally 0.020 inch, then the nominal effect
of printed circuit board grounding can be considered to
have already been included the published S parameters.
Package and Assembly Note
For detailed description of the device package, handling
and assembly, please refer to Application Note 5378.
ESD Precautions
Note: These devices are ESD sensitive. The following pre-
cautions are strongly recommended. Ensure that an ESD
approved carrier is used when die are transported from
one destination to another. Personal grounding is to be
worn at all times when handling these devices. For more
detail, refer to Avago Application Note A004R: Electro-
static Discharge Damage and Control.
