Description
M/A-COM’s MA05935-XXX is a miniature, phase-
locked, FM transmitter module. The MA05935-XXX is
ideally suited for rugged telemetry systems.
The MA05935-XXX contains a shock hardened crystal
oscillator, a silicon on sapphire phase-locked loop, and
an InGaP HBT VCO and power amplifier, with supply
line bypassing. The module requires only a single, posi-
tive regulated 3VDC power supply. The MA05935-XXX
has a fully matched (50W) output network.
M/A-COM's MA05935-XXX is fabricated on standard
FR-4 PC board material, employing automatic assembly
of the hybrid technology components (silicon on sap-
phire, InGaP HBT, and SMT). When fully encapsulated,
this module will easily survive high shock pulses greater
than 30,000G’s. This product is 100% RF tested to en-

Handling
Permanent damage to the MA05935-XXX may occur if the
following precautions are not adhered to:
A. Static Sensitivity – All die handling equipment and personnel
should comply with DOD-STD-1686 Class I.
B. Transients – Avoid instruments and power supply transients
while bias is connected to the MA05935-XXX. Use shielded
signal and bias cables to minimize inductive pick-up.
Mounting
DO NOT expose the MA05935-XXX to temperatures greater
than 180
°
C for more than 20 seconds. Higher temperatures
may result in reflow of the Sn63/Pb37 solder used for SMT
component attach.

Application Notes
DC connector
The DC connection of the MA05935-XXX is
made thru five single pin connectors. Each pin
is a thru hole of 0.020” diameter. The pin as-
signments are shown in the figure below.
The through-hole connector was chosen to al-
low freedom in mounting; this connector may
be either placed or omitted to allow use of other
connector types.

V 1.00
Channel Selection
The PLL determines the frequency of operation of
the transmitter. The channels available are listed in
the following tables. There are 32 frequencies avail-
able, at 1MHz spacing.
The channel selection on the board is performed
through the use of 0402 SMT zero ohm resistors,
connected to the parallel input lines of the PLL.
See the following pages for frequency choices, and
the required resistor positions.

The RF connector is a standard-sized,
through-hole mounted SSMC connector. To
afford user flexibility, the RF connector pro-
vided with the MA05935 is supplied unat-
tached to the board.
