HMC137 General Description

The HMC137 Bi-Phase Modulator is designed to phase-modulate an RF signal into reference and 180 degree states. Device input is at the RF port and out- put is at the LO port. The polarity of the bias current at the control port (IF port) defines the phase states. Excellent amplitude and phase balance provided by closely matched monolithic balun and diode circuits delivers 20 dB of carrier suppression in a tiny monolithic chip.

The device also functions as a demodulator or phase comparator. As a demodulator, data emerges at the control port when a modulated signal at the RF port is compared to a reference signal at the LO port. As a phase comparator, the phase angle between two signals applied to the RF and LO ports is represented by an analog voltage at the control port. Except for carrier suppression, the data presented here was measured under static conditions in which a DC bias current (nominally 5 mA) is applied to the control port.

HMC137 Features

Chip Integrates Directly into MIC Designs
20 dB of Carrier Suppression
Direct Modulation in the 6 - 11 GHz Band
Functions also as a Phase Detector

HMC137 Typical Application

The HMC137 is suitable for:
• Wireless Local Loop
• LMDS & VSAT
• Pt. to Pt. Radios
• Test Equipment

HMC141 General Description

The HMC141 chip is a minature double-balanced mixer which can be used as an upconverter or downconverter. The HMC142 is identical to the HMC141 except that the layout is a mirror image designed to ease integration into image-reject mixer modules. Broadband operation and excellent isolations are provided by on-chip baluns, which require no external components and no DC bias. The design is similar to the HMC143/144 mixers but without an IF combiner, providing a broad DC to 6 GHz IF bandwidth. These devices are much smaller and more reliable than hybrid diode mixers for VSAT and point-to-point radios.

HMC141 Maximum Ratings

LO Drive	+27 dBm
Storage Temperature	-65 to +150
Operating Temperature	-55 to +85

HMC141 Features

Input IP3: +21 dBm
LO / RF Isolation: 25 to 40 dB
IF Bandwidth: DC to 6 GHz
Small Size: 1.48mm x 1.48mm

HMC141 Typical Application

The HMC141 & HMC142 is ideal for:
• UNII & HiperLAN
• Microwave & MMW Radios
• Military, Space & Test Equipment

HMC141C8 General Description

The HMC141C8 is a miniature passive doublebalanced mixer in a non-hermetic ceramic surface mount package that can be used as an upconverter or downconverter. The device is a passive diode/balun type mixer with high dynamic range. The mixer can handle larger signal levels than most active mixers due to the high third order intercept of 20 dBm. MMIC implementation provides exceptional balance in the circuit resulting in high LO/RF and LO/IF isolations and unitto- unit consistency. This mixer has applications where small size and surface mount compatibility are important.

HMC141C8 Maximum Ratings

RF / IF Input	+13 dBm
LO Drive	+27 dBm
Storage Temperature	-65 to +150 °C
Operating Temperature	-55 to +85 °C

HMC141C8 Features

Input IP3: +21 dBm
Conversion Loss: 8.5 dB
LO to RF Isolation: 35 dB

HMC141C8 Typical Application

The HMC141C8 is ideal for:
• Microwave Pt to Pt Radios
• VSAT Ground Equipment
