HMC500LP3E HITTITE [Hittite Microwave Corporation], HMC500LP3E Datasheet - Page 6

• Manufacturer Part Number: HMC500LP3E
• Description: GaAs HBT VECTOR MODULATOR 1.8 - 2.2 GHz
• Manufacturer: HITTITE [Hittite Microwave Corporation]

Application Circuit
* Pins 15 & 16 are redundant I & Q inputs.
Gain and Phase control are applied through the I and Q control ports. For a given linear gain (G) and phase (θ) setting, the
voltages applied to these ports in all measurements are calculated as follows:
Where Vmi and Vmq are the I and Q voltage settings corresponding to maximum isolation at room temperature and F = 2 GHz.
Note that G=10
