Product Description
The VG024 is a wideband high dynamic range variable gain
amplifier (VGA) packaged in a SOIC-8 surface-mount
package. The +21 dBm output compression point and +37
dBm output intercept point of the amplifier are maintained
over the entire attenuation range, making the VG024 ideal
for use in temperature compensation circuits. With the
suggested driver circuit there can be independent gain slope
and offset control for compensating RF chains with many
amplifier stages. Other attenuator driver circuits give more
functionality to this MCM and can be found in the
application notes.
Superior thermal design allows the product to have a
minimum MTTF rating of 100 years at a mounting
temperature of +85o C. All devices are 100% RF & DC
tested and packaged on tape and reel for automated surface-
mount assembly.

Test conditions unless otherwise noted.
1. T = 25oC, Vdd = +5 V, Frequency = 800 MHz in an application circuit.
2. 3OIP measured with two tones at an output power of +10 dBm/tone separated by 10 MHz. The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. Frequency 240-1000 MHz max 6dB at 70 MHz and 7dB at 2.2 GHz T = 25oC
4. Frequency 70-1000 MHz min gain control pin current 15mA 11 dB at 2.2 GHz depending on maximum gain control pin current
5. The max junction temperature ensures a minimum MTBF rating of 1 million hours of usage.
