Product Overview
The Mini-Circuits HVA series, surface mount, constant impedance voltage variable attenuators provide excellent attenuation
and linearity performance while maintaining constant RF impedance across the attenuation range. Built using Mini-Circuits
proven shielded module construction technology, these models integrate dual pin diodes along with internal 90 degree hybrids.
This termination insensitive approach allows more exibility so designers can locate the attenuators anywhere in their lineup,
including cascading VVAs for true attenuation addition without VSWR interaction degrading the usable attenuation range.
Feature
Advantages
Constant Impedance
(Termination insensitive)
The HVA series VVA incorporates 90° hybrids to buffer internal circuits from source and load mismatch. This
unique feature enables the HVA series to maintain performance independent of source and load impedance,
and allows units to be cascaded with true additive attenuation.
Excellent atness
Typical attenuation atness less than 1 dB typ. across the full band from 0 to 30 dB attenuation is great for
feed forward applications.
Monotonic Response
Monotonic response (0 to 2.5V) makes a great selection for ALC circuits
Return Loss
22 dB typ return loss across frequency and control voltage ranges provides an excellent match under all
operating conditions allowing straightforward cascading.
High IP3
High +50 dBm IP3 typ. at min attenuation and +40 dBm typ. up to 2.5V allows exibility to locate VVA in
lineup where attenuation is required the most without degrading system linearity.
Key Features
