HMC595 / 595E
GaAs MMIC 3 WATT T/R SWITCH,
DC - 3 GHz
v00.0805
General Description
Features
Functional Diagram
Low Insertion Loss: 0.3 dB
High Input IP3: +65 dBm
Isolation: 30 dB
Positive Control: 0/+3V to 0/+10V
Ultra Small Package: SOT26
Included in the HMC-DK005 Designer’s Kit
Electrical Speci cations,
TA = +25° C, Vctl = 0/+5 Vdc (Unless Otherwise Stated), 50 Ohm System
Typical Applications
The HMC595 / HMC595E is ideal for:
• Cellular/3G Infrastructure
• Private Mobile Radio Handsets
• WLAN, WiMAX & WiBro
• Automotive Telematics
• Test Equipment
The HMC595 & HMC595E are low-cost SPDT swit-
ches in 6-lead SOT26 packages for use in transmit/
receive applications which require very low distortion
at high incident power levels. The device can control
signals from DC to 3 GHz and is especially suited
for Cellular/3G infrastructure, WiMAX and WiBro
applications with only 0.3 dB typical insertion loss.
The design provides a 3 watt power handling and
+65 dBm third order intercept at +8 Volt bias. RF1
and RF2 are re ective shorts when “Off”. Control
inputs A & B are compatible with CMOS and some
TTL logic families. These products are form,  t and
function replacements for HMC195 & HMC195E while
offering superior electrical performance.

Typical Application Circuit
Notes:
1. Set logic gate and switch Vdd = +3V to +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 of +3 to +8 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 V set to +10V. The switch will operate properly (but at lower RF power
capability) at bias voltages down to +3V.
Pin Descriptions

Evaluation Circuit Board
The circuit board used in the  nal application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF port should have 50
ohm impedance and the package ground leads and
package bottom should be connected directly to the
ground plane similar to that shown above. The eval-
uation circuit board shown above is available from
Hittite Microwave Corporation upon request.
