HMC270MS8G General Description

The HMC270MS8G is a broadband non-refl ective GaAs SPDT switch in an 8 lead MSOP grounded base surface mount plastic package. Covering DC to 8 GHz, the switch offers excellent isolation from 70 to 35 dB. The negative control voltage of -5 volts allows operation down to DC. If positive control is required along with high isolation, see the DC to 3.5 GHz HMC284MS8G non-refl ective SPDT.

HMC271LP4 General Description

The HMC271LP4 & HMC271LP4E are broadband 5- bit positive control GaAs IC digital attenuators with serial-to-parallel drivers in low cost leadless QFN 4x4 mm SMT packages. Covering 0.7 to 3.7 GHz, the insertion loss is typically less than 2.5 dB. The attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB for a total attenuation of 31 dB. Accuracy is excellent at ± 0.4 dB typical with an IIP3 of up to +48 dBm. Five bit CMOS compatible serial control words are used to select each attenuation state. A single Vcc bias of +3V to +5V applied through an external 5k Ohm resistor is required.

HMC271LP4 Maximum Ratings

Digital Inputs (Reset , Shift Clock, Latch Enable & Serial In)	-1.5 to (Vcc + 1.5) Vdc
Digital Outputs (Serial Out)	-0.5 to (Vcc+0.5)Vdc
DC Current on Serial Output	±35mA
Bias Voltage (Vcc)	+7.0 Vdc
Storage Temperature	-65 to +150
Operating Temperature	-40 to +85
RF Input Power (0.7 - 3.7 GHz)	+26 dBm
ESD Sensitivity (HBM)	Class 1A
