Insertion loss of the reference was very low and generally,
increased with frequency (Figure 21). If the demo-board
has been constructed carefully, there should not be any
evidence of resonance. The reference line’s insertion loss
trace can be stored in the VNA’s display memory and
used to correct for the insertion loss of the test line in the
subsequent measurements.
Figure 1. Insertion loss of reference line.
To evaluate the HMPP-389T as shunt switch, it was
mounted on the test line and then the appropriate bias-
ing voltage was applied. In our prototype, the worst case
return loss was 10 dB at 5 GHz (Figure 22). The return loss
varied very little when the bias was changed from zero
to -20V.
Figure . Return loss of HMPP-389T mounted on test line at 0V and -0V
bias.
Normalization was used to remove the pcb’s and connec-
tors’ losses from the measurement of the shunt switch’s
loss. The active trace was divided by the memorized
trace (Data/Memory) to produce the normalized data.
At zero bias, the insertion loss was under 0.6 dB up to 6
GHz (Figure 23). Applying a reverse bias to the PIN diode
has the effect of reducing its parasitic capacitance. With a
reverse bias of -20V, the insertion loss improved to better
than 0.5 dB (Figure 24).

The PIN diode’s resistance is a function of the bias current.
So, at higher forward current, the isolation improved.
The combination of the HMPP-389T and the SK063A
demoboard exhibited more than 17 dB of isolation from
1 to 6 GHz at If ≥ 1mA (Figure 25).
Figure 5. Isolation at different frequencies with forward current as a
parameter.
The combination of the HMPP-389T and the demo-board
allows a high performance shunt switch to be constructed
swiftly and economically. The extremely low parasitic
inductance of the package allows the switch to operate
over a very wide frequency range.
