I'm using the HMC980, with the ALMH and ALML pins directly connected to ISET (not used).  The data sheet indicates that a 5 k ISET resistor to ground is required and I've found that the device will not work without it. I'm wondering why is it needed if the ALM is not used, and is the resistor tolerance still critical?
