HMC199MS8 / 199MS8E
DUAL SPDT SWITCH
DC - 2.5 GHz
v04.0404
General Description
Features
Functional Diagram
RoHS-Compliant Product
Integrated Dual SPDTs
Low Insertion Loss: <0.5 dB @ 2 GHz
Positive Control: 0/+5V
Ultra Small MSOP8 Package: 14.8 mm2
Electrical Speci cations, TA = +25° C, Vctl = 0/+5 Vdc, 50 Ohm System
Typical Applications
The HMC199MS8 / 199MS8E is ideal for:
• Cellular
• ISM Basestations
• PCS
The HMC199MS8 & HMC199MS8E are low-cost
general purpose dual SPDT GaAs “bypass” switches
in 8-lead MSOP packages covering DC to 2.5 GHz.
These four-RF- port components integrate two SPDT
switches and a through line onto a single IC. The
designs provide low insertion loss of less than 0.5
dB while switching passive or active external cir-
cuit components in and out of the signal path. Port
to port isolations are typically 25 to 30 dB. On-chip
circuitry enables positive voltage control operation at
very low DC currents with control inputs compatible
with CMOS and most TTL logic families. Applications
include LNA or  lter bypass switching and single bit
attenuator switching. The HMC199MS8E is a RoHS-
compliant product.

Typical Application Circuit
Notes:
1. Set A/B control to 0/+5V, Vdd = +5V and use HCT series logic to provide a TTL driver interface.
2. Control inputs A/B can be driven directly with CMOS logic (HC) with Vdd = 5 to 7 Volts applied to the CMOS logic gates.
3. DC Blocking capacitors are required for each RF port as shown. Capacitor value determines lowest frequency of operation.
4. Highest RF signal power capability is achieved with Vdd = +7V and A/B set to 0/+7V.
5. For further information refer to “Using the HMC199MS8 as a Low-Cost 1-Bit Attenuator” product note.
